Description

CSI reporting method, device and system

The present application claims to submit chinese patent applications with the application number of 201810866456.4 and the application name of "a CSI adjusting method" on year 2018, 08 and 01, and to submit priority of chinese patent applications with the application number of 201811298539.4 and the application name of "an information reporting method and terminal" on year 2018, 11 and 02, wherein the entire contents of the applications are incorporated by reference in the present application.

Technical Field

The embodiment of the present application relates to the field of communications technologies, and in particular, to a method, an apparatus, and a system for reporting Channel State Information (CSI).

Background

In a fourth generation (4G) communication system (which may also be referred to as a Long Term Evolution (LTE) communication system), a terminal device completes CSI measurement through a CSI-RS (channel state information-reference signal) configured for measurement, and reports CSI to a base station through a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH), where the content of the CSI includes Channel Quality Indicator (CQI) or Rank Indicator (RI), and the like. Since the reported CSI may not be matched with the channel quality of the current transmission channel, the terminal device or the base station may adjust the value of the CQI in the reported CSI according to the condition of an Acknowledgement (ACK) and/or a Negative Acknowledgement (NACK) sent or received within a specific time period. However, the adjustment mechanism must be based on the situation of data transmission between the terminal device and the base station in a specific time period, that is, the sending situation of ACK and/or NACK corresponding to the data transmission, and if data transmission is not performed between the terminal device and the base station in the specific time period, the adjustment mechanism fails to function, and does not perform a function of correcting the reported CQI value.

In a fifth generation (5G) communication system (which may also be referred to as a New Radio (NR) communication system) or a high-frequency scenario (e.g., a frequency band above 6 gigahertz (GHz)) of a communication system after 5G, signals may be transmitted between a base station and a terminal equipment (UE) through a millimeter wave frequency band. Because the millimeter wave frequency band has the characteristics of large attenuation and weak diffraction capability, the problems of obvious signal fading, increased path loss and the like are easily caused by transmitting signals through the millimeter wave frequency band. To avoid these problems, signals are transmitted between the base station and the terminal device by analog beamforming techniques, such as: the terminal equipment can concentrate signals on one transmitting beam to transmit to the base station, and the base station can receive the signals on a receiving beam corresponding to the transmitting beam, so that the channel quality of a transmission channel between the base station and the terminal equipment is improved, and the problems of obvious signal fading, increased path loss and the like caused by high-frequency communication are solved. The above adjustment mechanism for adjusting the reported CQI value in the 4G system has the same problem when applied to these high frequency scenarios.

Detailed Description

The CSI reporting method provided in the embodiment of the present application may be applied to a communication system supporting high frequency communication, where the communication system may be a 4G communication system or an LTE system, may also be a 5G mobile communication system or an NR communication system, and may also be other next generation communication systems, without limitation. The method provided by the embodiment of the present application is described below by taking the communication system shown in fig. 1 as an example.

Fig. 1 is a schematic architecture diagram of a communication system according to an embodiment of the present application, and as shown in fig. 1, the communication system may include: the access network equipment and the terminal equipment, the terminal equipment is located in the coverage area of the access network equipment, and the terminal equipment can mutually transmit data or information with the access network equipment in a high-frequency communication mode, such as: the terminal equipment can receive the CSI-RS issued by the access network equipment, complete the measurement of the CSI-RS to obtain the CSI, and report the CSI to the access network equipment.

Under the scene of high-frequency communication between the terminal equipment and the access network equipment, the terminal equipment and the access network equipment can form a plurality of beam pairs between the terminal equipment and the access network equipment by utilizing a beam forming technology, and data is transmitted and received on the beam pairs. For example, as shown in fig. 1, a terminal device may generate a plurality of receiving beams by using a beamforming technique, an access network device may generate a plurality of transmitting beams by using a beamforming technique, a transmitting beam of the access network device is aligned with a receiving beam of the terminal device, the access network device may transmit data or information to the terminal device by using the transmitting beam, and the terminal device may receive the data or information transmitted by the access network device on the receiving beam corresponding to the transmitting beam.

The terminal equipment (terminal equipment) may be referred to as a terminal (terminal) or a User Equipment (UE), or a Mobile Station (MS) or a Mobile Terminal (MT), for example: the device may be a mobile phone, a tablet Computer, a desktop Computer, a laptop Computer, a handheld Computer, a notebook Computer, a Personal Computer (PC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), a wearable device (such as a smart watch), a smart home device, a vehicle-mounted Computer, etc., and the embodiment is not limited to a specific form of the device. In this embodiment of the present application, the apparatus for implementing the function of the terminal device may be the terminal device, or may be an apparatus capable of supporting the terminal device to implement the function, for example, a chip system. The following describes a technical solution provided in an embodiment of the present application, by taking only an example that a device for implementing a function of a terminal device is the terminal device.

The access network device may be referred to as a network device, and is mainly used for implementing functions such as a wireless physical control function, resource scheduling and wireless resource management, wireless access control, and mobility management. Specifically, the access network device may be AN Access Network (AN)/Radio Access Network (RAN) device, or a device composed of a plurality of 5G-AN/5G-RAN nodes, or any one of a base station (NB), AN evolved node b (eNB), a next generation base station (gbb), a transmission point (TRP), a Transmission Point (TP), and some other access node. In this embodiment of the application, the apparatus for implementing the function of the network device may be an access network device, or may be an apparatus capable of supporting the access network device to implement the function, such as a chip system, without limitation.

In the research of the applicant, it is found that in a high-frequency scene, the directivity of a beam is easily affected by factors such as shielding and movement, when there is shielding between a terminal device and a base station or the terminal device rotates, a receiving beam used by the terminal device is likely to be not aligned with a transmitting beam used by the base station, and the channel quality of a transmission channel between the base station and the terminal device is obviously reduced, thereby causing a series of problems. For example, in the high-frequency scenario shown in fig. 1, in the process that the terminal device measures the configured CSI-RS to complete the CSI measurement, and reports the CSI through the PUCCH or PUSCH, the terminal device needs a period of time to calculate the CSI after measuring the CSI-RS, and reports the CSI in the configured or indicated slot, if the terminal device rotates between the time point of measuring the CSI-RS and the time point of reporting the CSI, which results in that the receiving beam used by the terminal device is not aligned with the transmitting beam used by the base station, the channel quality of the transmission channel represented by the CSI reported by the terminal device may be inconsistent with the channel quality of the transmission channel used by the base station when the base station actually performs data transmission, and at this time, the base station determines information such as a Modulation and Coding Scheme (MCS) according to the CSI reported by the terminal device, the channel requirement of the transmission channel during actual data transmission may not be met, and the terminal device using the MCS information may cause the terminal device to fail demodulation or to successfully demodulate but to have a low throughput.

For example, as shown in fig. 2, when the terminal device measures the CSI-RS sent by the base station, the receiving beam direction used by the terminal device is aligned with the transmitting beam direction used by the base station, and the channel quality of the transmission channel between the two is better. If the terminal device rotates in the process of obtaining the CSI by the terminal device according to the CSI-RS calculation, the direction of the receiving beam used by the terminal device is no longer aligned with the direction of the transmitting beam used by the base station, and the channel quality of the transmission channel between the receiving beam and the transmitting beam is deteriorated. At this time, after the terminal device reports the CSI, the base station may allocate a higher MCS to the terminal device according to the CSI, so that the terminal device finally fails to demodulate a Physical Downlink Shared Channel (PDSCH) according to the too high MCS.

In order to solve the above problem, in this embodiment of the present application, before reporting the CSI, the terminal device may determine whether itself rotates, and obtain a CQI offset value according to at least its rotation state information when the terminal device rotates, adjust the CQI included in the CSI by using the CQI offset value, and report the CSI including the adjusted CQI to the access network device, specifically, the implementation process may be described in an embodiment corresponding to fig. 4.

It should be noted that fig. 1 is only an exemplary drawing, the number of devices included in fig. 1 is not limited, and the communication architecture may include other devices besides the devices shown in fig. 1, such as: core network devices, data networks, etc. may also be included. In addition, names of the respective devices in fig. 1 are not limited, and the respective devices may be named by other names in addition to the names shown in fig. 1 without limitation.

In some embodiments, the angular velocity of the communication device 100 about three axes (i.e., x, y, and z axes) may be determined by the gyro sensor 1201. The gyro sensor 1201 may be used to photograph anti-shake. Illustratively, when the shutter is pressed, the gyro sensor 1201 detects the shake angle of the communication device 100, calculates the distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the communication device 100 through a reverse movement, thereby achieving anti-shake.

The acceleration sensor 1203 may detect the magnitude of acceleration of the communication device 100 in various directions (typically three axes). The magnitude and direction of gravity can be detected when the communication device 100 is stationary. The method can also be used for recognizing the posture of the electronic equipment, and is applied to horizontal and vertical screen switching, pedometers and other applications.

The gravity gauge sensor 1204 is a cantilever type displacement device made of an elastic sensitive element, and an energy storage spring made of the elastic sensitive element is used for driving an electric contact to complete the conversion from the gravity change to the electric signal. By measuring the acceleration due to gravity by means of a gravity sensor, the tilt angle of the device with respect to the horizontal can be calculated, such as: the mobile phone with gravity sensing can sense the screen state and automatically adjust the screen to keep the screen horizontal.

Fig. 4 is a CSI reporting method provided in the embodiment of the present application, and as shown in fig. 4, the CSI reporting method may include:

step 401: before reporting the CSI, the terminal equipment determines whether the terminal equipment rotates; if the terminal equipment is determined to rotate, executing the step 402 to the step 404; and if the terminal equipment does not rotate, reporting the CSI to the network equipment.

The CSI is channel state information, the CSI may be obtained by the terminal device according to CSI-RS measurement issued by the network device, and the CSI may include CQI, RI, and other information. The terminal device may use existing measurements to obtain CSI, such as: the terminal device may measure the CSI-RS issued by the network device, and calculate the CSI according to the measurement result. The CSI reporting method provided in the embodiment of the present application is described by taking the adjustment of the CQI included in the CSI as an example, it can be understood that when the terminal device moves, only the CQI included in the CSI is not limited to be adjusted, and values of other information included in the CSI can be adjusted, for example: the value of RI included in CSI may be adjusted. The manner of adjusting the values of other information included in the CSI may refer to the manner shown in fig. 4, and is not described again.

The rotation of the terminal device may refer to the rotation of the terminal device in situ, or the rotation of the terminal device during the moving process, without limitation. In the embodiment of the application, the terminal equipment can detect the state of the sensor mounted on the terminal equipment and determine whether the terminal equipment rotates or not according to the state of the sensor. The sensors may include, but are not limited to, gyroscope sensors, gravity sensors, acceleration sensors, magnetic force sensors, and the like.

Specifically, the actions involved in step 401 may be performed interactively by a processor of the terminal device and a sensor of the terminal device. Such as: the processor of the terminal equipment can control the sensor of the terminal equipment to collect a numerical value in a first time period and send the collected numerical value to the terminal equipment for processing, the processor of the terminal equipment obtains the numerical value collected by the sensor of the terminal equipment in the first time period, and if the processor of the terminal equipment determines that the numerical value collected by at least one sensor changes and the change amplitude of the numerical value is greater than a first threshold value, the terminal equipment is determined to rotate; on the contrary, if the value acquired by each sensor in the sensors of the terminal equipment is fixed and unchanged, or the value acquired by at least one sensor in the sensors of the terminal equipment changes, and the change amplitude of the value is smaller than or equal to the first threshold, it is determined that the terminal equipment does not rotate.

The first time period may be a time period from the terminal device measuring the obtained CSI to the terminal device reporting the CSI. The first threshold may be set as needed, without limitation. If the variation amplitude of the value acquired by the sensor is larger than the first threshold value, the terminal equipment is indicated to be rotated very probably, otherwise, the terminal equipment is not rotated.

For example, assuming that the terminal device completes CSI measurement at a time t1 equal to 10ms, and needs to perform CSI reporting at a time t2 equal to 15ms, the first threshold is set to 0.1, and the terminal device may perform CSI reporting at multiple times of a period t1 to t2, such as: reading values acquired by sensors (a gyroscope sensor or a gravity sensor or an acceleration sensor or a magnetic sensor) at multiple moments such as 11ms, 12ms, 13ms and the like, wherein if the value of any sensor (such as the gravity sensor) changes, the values are as follows: 9.8m/s 2, 9.5m/s 2, 9.3m/s 2, with a variation of 0.3m/s 2, greater than 0.1, it is determined that the terminal device has rotated.

Step 402: and the terminal equipment obtains the compensation value of the CQI at least according to the rotation state information of the terminal equipment.

The offset value of the CQI may be used to adjust the CQI included in the CSI measured by the terminal device, for example: the method and the device can be used for adjusting a value of a CQI included in the CSI, or adjusting a value of a signal to interference and noise ratio (SINR) corresponding to the CQI. In the embodiment of the present application, the offset value of the CQI may be a fixed value or a dynamically changing value, and the offset value of the CQI may be a positive value or a negative value, which is not limited.

The rotation state information of the terminal device may be used to represent a rotation condition of the terminal device, and the rotation state information of the terminal device may include a rotation speed of the terminal device, or a rotation direction of the terminal device, or the rotation speed of the terminal device and the rotation speed of the terminal device.

The rotation speed of the terminal device may be determined by the angular velocity of the terminal device and/or the acceleration of the terminal device, the greater the rotation speed of the terminal device, and conversely, the smaller the angular velocity of the terminal device and/or the acceleration of the terminal device, the smaller the rotation speed of the terminal device. The rotation speed of the terminal device may determine the absolute value of the compensation value of the CQI, such as: the larger the rotation speed of the terminal equipment is, the larger the compensation value of the CQI is, and conversely, the smaller the rotation speed of the terminal equipment is, the smaller the absolute value of the compensation value of the CQI is.

Taking the case that the rotation speed of the terminal device is determined by the angular velocity of the terminal device and the acceleration of the terminal device, the gravity sensor of the terminal device can acquire the acceleration of the terminal device and report the acceleration to the processor of the terminal device, the gyroscope sensor of the terminal device acquires the angular velocity of the terminal device and reports the angular velocity to the processor of the terminal device, and the processor of the terminal device calculates the rotation speed of the terminal device according to the acceleration of the terminal device and the angular velocity of the terminal device.

The rotation direction of the terminal device may include that the terminal device is close to the beam center of the transmission beam or that the terminal device is far from the beam center of the transmission beam. The rotation direction of the terminal device may determine the positive and negative of the compensation value of CQI, such as: the corresponding relation between the rotation direction of the terminal equipment and the compensation value of the CQI satisfies the following conditions: the CQI offset value is a positive value if the terminal device is close to the beam center of the transmission beam, and a negative value if the terminal device is far from the beam center of the transmission beam.

The beam center of the receive beam may refer to a direction of the strongest beam gain or the strongest signal strength on the receive beam, and the beam center of the transmit beam may refer to a direction of the strongest beam gain or the strongest signal strength on the transmit beam. As shown in fig. 5a, the rotation direction a is the beam center where the terminal device approaches the transmission beam, and the rotation direction B is the beam center where the terminal device moves away from the transmission beam.

It should be noted that, in the embodiments of the present application, a transmission beam may refer to a beam transmitted by a network device to a terminal device, and a reception beam may refer to a beam for the terminal device to receive data or information or a reference signal transmitted by the network device.

Illustratively, the terminal device may determine the rotation direction of the terminal device through three ways:

the first method is as follows: and the terminal equipment determines the rotation direction of the terminal equipment according to the power value measured in the continuous time.

Such as: and if the power value measured by the terminal equipment in the continuous time is increased, determining that the rotation direction of the terminal equipment is close to the beam center of the transmission beam, and otherwise, keeping away from the beam center of the transmission beam.

The second method comprises the following steps: the terminal device determines the rotation direction of the terminal device according to the positive and negative values of the angular velocity value acquired by the gyro sensor (or other sensors) of the terminal device, the beam center direction of the transmission beam, and the beam center direction of the reception beam.

For example, as shown in fig. 5B, with the coordinate axis of the gyroscope of the terminal device as a reference system, the terminal device rotates around the x axis, the angle between the beam center direction of the transmission beam and the positive direction of the coordinate axis y is a, the angle between the center direction of the reception beam and the positive direction of the coordinate axis y is B, if the difference between a and B is a positive value and the angular velocity on the y axis is a positive value, or the difference between a and B is a negative value and the angular velocity on the y axis is a negative value, the rotation direction of the terminal device may be considered to be close to the beam center of the transmission beam, otherwise, the rotation direction of the terminal device may be considered to be away from the beam center of the transmission beam.

The third method comprises the following steps: and the terminal equipment predicts and obtains the rotation direction of the terminal equipment at the next moment by using methods such as machine learning and the like according to the information such as the historical posture, the current communication environment, the service scene and the like of the terminal equipment.

The historical posture of the terminal device may refer to a historical rotation direction of the terminal device. For example, the terminal device may store the rotation direction of the terminal device determined in the first or second manner as history data in a database, and when the third manner is performed, the terminal device may obtain the history posture of the terminal device from the database.

For example, if the terminal device is turned in a direction away from the beam center of the transmission beam for a long period of time, it can be determined that the terminal device is away from the beam center of the transmission beam by machine-learning the historical posture of the terminal device.

In step 402, the terminal device obtains the compensation value of the CQI at least according to the rotation state information of the terminal device, which may include the following two possible implementation manners:

in a possible implementation manner, the terminal device obtains the compensation value of the CQI according to the rotation state information of the terminal device. In particular, this implementation may be described with reference to the first scenario of the method illustrated in fig. 4, described below.

In another possible implementation manner, the obtaining, by the terminal device, the compensation value of the CQI according to at least the rotation state information of the terminal device may include: the terminal device obtains the compensation value of the CQI according to the rotation state information of the terminal device and other information (e.g., the receiving beam state information of the terminal device). In particular, this implementation may be described with reference to the second scenario of the method illustrated in fig. 4, described below.

In particular, the actions referred to in step 402 may be performed by a processor of the terminal device.

Step 403: and the terminal equipment adjusts the CQI by using the compensation value of the CQI.

In one example, adjusting the CQI by the terminal device with the offset value of the CQI can include: the terminal equipment adds the compensation value of the CQI and the CQI included in the CSI (or the SINR corresponding to the CQI included in the CSI) to obtain the adjusted CQI.

For example, taking the example that the terminal device adds the offset value of the CQI and the SINR corresponding to the CQI included in the CSI to obtain the adjusted CQI, if the offset value of the CQI determined in step 402 is 1 and the SINR corresponding to the CQI included in the CSI is 7dB, the adjusted SINR is 7+1 to 8dB, and then the terminal device may report the CQI corresponding to the SINR of 8dB to the network device as the adjusted CQI.

In yet another example, the adjusting the CQI by the terminal device using the offset value of the CQI may include: the terminal device adds the CQI offset value calculated in step 402 to the CQI offset value used for adjusting the CQI last time to obtain an accumulated offset value, and adds the accumulated offset value to the CQI included in the CSI (or the SINR corresponding to the CQI included in the CSI) to obtain an adjusted CQI.

The accumulated offset value may be an offset value of CQI used for adjusting CQI (or SINR corresponding to CQI) last time. Such as: the offset value used for adjusting the CQI last time is Q (t-1), and the cumulative offset value used for adjusting the CQI this time may be Q (t) ═ Q (t-1) + the offset value of the CQI calculated in step 402. In the embodiment of the present application, the initialized accumulated compensation value may be 0 or a preset value, which is not limited.

For example, taking the case where the SINR corresponding to the CQI included in the CSI is added to the cumulative offset value to obtain the adjusted CQI, if the offset value of the CQI determined in step 402 is 1, the offset value of the CQI used for adjusting the CQI last time is 3dB, and the SINR corresponding to the CQI included in the CSI is 7dB, the cumulative offset value is 3+1 to 4dB, and the adjusted SINR is 7+4 to 11dB, and then the terminal device may report the CQI corresponding to the SINR of 11dB as the adjusted CQI to the network device.

In particular, the actions referred to in step 403 may be performed by a processor of the terminal device.

Step 404: and the terminal equipment reports the CSI comprising the adjusted CQI to the network equipment.

For example, the network device may be the access network device in fig. 2, and the reporting, by the terminal device, the CSI including the adjusted CQI to the access network device may include: and the terminal equipment includes the CSI including the adjusted CQI in a PUSCH or PUCCH and reports the CSI to the access network equipment.

Specifically, the actions involved in step 404 may be performed by a processor of the terminal device controlling a wireless communication module of the terminal device. Such as: the processor of the terminal device may send the CSI including the adjusted CQI to the wireless communication module of the terminal device, and the wireless communication module of the terminal device reports the CSI to the network device through the antenna of the terminal device.

Based on the method shown in fig. 4, the terminal device may determine whether the terminal device rotates before reporting the CSI, determine a compensation value of the CQI according to at least the rotation state information of the terminal device after determining that the terminal device rotates, adjust the CQI included in the CSI by using the determined compensation value of the CQI, and report the CSI including the adjusted CQI to the network device. Therefore, the problem that the reported CSI is inconsistent with the CSI during actual data transmission due to rotation of the terminal equipment during the period from the CSI measurement to the CSI reporting can be avoided, and the network equipment allocates too high or too low MCS according to the CSI reported by the terminal equipment, so that the probability of data transmission failure is reduced, and the throughput of the terminal equipment is improved.

In a first scenario of the method shown in fig. 4, in step 402, the step of obtaining, by the terminal device, a CQI offset value according to at least the rotation state information of the terminal device includes: and the terminal equipment obtains the compensation value of the CQI at least according to the first corresponding relation and the rotation state information of the terminal equipment.

The first corresponding relationship may be configured to the terminal device by the network device, or may be predefined by a protocol. The embodiment of the present application does not limit the specific form of the first corresponding relationship, the first corresponding relationship may be a list-form corresponding relationship, or may also be a data-form or other form corresponding relationship, and the embodiment of the present application only describes the first corresponding relationship as a list-form corresponding relationship as an example.

The first correspondence may include a correspondence between a rotation speed of the terminal device and/or a rotation direction of the terminal device and a compensation value of the CQI. Such as: the first corresponding relationship may include a corresponding relationship between the rotation speed of the terminal device and the compensation value of the CQI, or the first corresponding relationship includes a corresponding relationship between the rotation direction of the terminal device, the rotation speed of the terminal device and the compensation value of the CQI. That is, the correspondence between the rotation direction of the terminal device and the compensation value of the CQI and the correspondence between the rotation speed of the terminal device and the compensation value of the CQI may be located in the same correspondence list or may be located in different correspondence lists.

The corresponding relation between the rotating speed of the terminal equipment and the compensation value of the CQI satisfies the following conditions: the larger the rotation speed of the terminal equipment is, the larger the absolute value of the compensation value of the CQI corresponding to the rotation speed is.

The corresponding relation between the rotation direction of the terminal equipment and the compensation value of the CQI satisfies the following conditions: the terminal equipment is close to the beam center of the transmission beam, the compensation value of the CQI is a positive value, the terminal equipment is far away from the beam center of the transmission beam, and the compensation value of the CQI is a negative value. Such as: when the terminal device approaches the beam center of the transmission beam, the beam center of the reception beam of the terminal device is gradually aligned with the beam center of the transmission beam, the channel quality gradually becomes better, and the compensation value of the CQI may be a positive value.

For example, the terminal device may query the first corresponding relationship with the rotation state information of the terminal device as an index, and use the offset value of the CQI corresponding to the rotation state information of the terminal device in the first corresponding relationship as the finally determined offset value of the CQI.

For example, taking the correspondence between the rotation direction of the terminal device and the offset value of the CQI and the correspondence between the rotation speed of the terminal device and the offset value of the CQI as examples, which belong to different lists, the following table first shows the correspondence between the rotation speed of the terminal device and the absolute value of the offset value of the CQI, and the following table second shows the correspondence between the rotation direction of the terminal device and the offset value of the CQI, as shown in table one, when the rotation speed of the terminal device is 0rpm to 30rpm, the absolute value of the offset value of the CQI may be 0.2, and when the rotation speed of the terminal device is 60rpm to 120rpm, the absolute value of the offset value of the CQI may be 1.5, which is greater than the absolute value of the offset value of the CQI when the rotation speed is 0rpm to 30 rpm. As shown in table two, the offset value of the CQI corresponding to the beam center at which the terminal device is close to the transmission beam is positive, and the offset value of the CQI corresponding to the beam center at which the terminal device is far from the transmission beam is negative. And combining the table I and the table II, when the rotating speed of the terminal equipment is 50rpm and the rotating direction of the terminal equipment is close to the beam center of the transmitting beam, the compensation value of the CQI can be determined to be 1 by inquiring the table I and the table II, and when the rotating speed of the terminal equipment is 50rpm and the rotating direction of the terminal equipment is far away from the beam center of the transmitting beam, the compensation value of the CQI can be determined to be-1 by inquiring the table I and the table II.

Watch 1

Speed of rotation (rpm) of terminal equipment	Absolute value of offset value of CQI
		0～30	0.2
30～60	1
		60～120	1.5
Over 120	2

Watch two

For another example, if the correspondence relationship between the rotation direction of the terminal device and the offset value of the CQI and the correspondence relationship between the rotation speed of the terminal device and the offset value of the CQI are included in the same list, as shown in table three, for example, when the rotation direction is close to the beam center of the transmission beam, the offset value of the CQI is 0.2 when the rotation speed of the terminal device is 0rpm to 30rpm, and the offset value of the CQI is 1.5 when the rotation speed of the terminal device is 60rpm to 120rpm, which is larger than the offset value of the CQI when the rotation speed is 0rpm to 30 rpm. And under the condition that the rotation direction is far away from the beam center of the transmission beam, when the rotation speed of the terminal equipment is 0 rpm-30 rpm, the compensation value of the CQI is-0.05, and when the rotation speed of the terminal equipment is 60 rpm-120 rpm, the compensation value of the CQI is-1.2, and the absolute value of the compensation value is larger than that of the CQI when the rotation speed is 0-30 rpm.

Watch III

Therefore, the terminal equipment can dynamically determine the compensation value of the CQI according to the rotation direction of the terminal equipment and the rotation speed of the terminal equipment, and the measured CQI is adjusted by using the determined compensation value of the CQI, so that the adjusted CQI can be suitable for the situation that the terminal equipment rotates, the channel quality of a transmission channel after the terminal equipment rotates is matched, and the network side is prevented from allocating too high or too low MCS to the terminal equipment.

In the second scenario of the method shown in fig. 4, in addition to determining the compensation value of CQI according to the rotation status information of the terminal device, the terminal device needs to combine other information, such as: and receiving the beam parameter information of the terminal equipment, and jointly determining the compensation value of the CQI. Such as: the obtaining, by the terminal device, the compensation value of the CQI according to at least the rotation state information of the terminal device may include:

and the terminal equipment obtains a compensation value of the CQI at least according to the rotation state information and the receiving beam parameter information of the terminal equipment.

The rotation state information of the terminal equipment comprises the rotation direction of the terminal equipment; the above description of the rotation direction of the terminal device can be referred to, and is not repeated.

The receiving beam parameter information may include, but is not limited to, a beam width of the receiving beam and/or a polarization manner of the receiving beam. The beamwidth of a receive beam may refer to the beamwidth of a 3dB beam in the angular domain, for example, the beamwidth of a certain receive beam may be around 20 degrees. The corresponding relation between the beam width of the receiving beam and the compensation value of the CQI satisfies the following conditions: the larger the beam width of the reception beam, the smaller the absolute value of the offset value of the corresponding CQI. Such as: the wider the beam width of the receiving beam of the terminal device is, the higher the robustness of the receiving beam is, the more stable the receiving beam is, even if the terminal device rotates, the center position of the receiving beam of the terminal device is not necessarily aligned with the center position of the transmitting beam, but the center position of the receiving beam of the terminal device may be located within the range of 3dB beam width of the transmitting beam, the channel variation may not be too large, and the absolute value of the compensation value of CQI may be smaller, whereas if the beam width of the receiving beam is narrower, the center position of the receiving beam of the terminal device is easily deviated from the range of 3dB beam width of the transmitting beam after the terminal device rotates, the channel variation is larger, and the absolute value of the compensation value of CQI is larger.

The polarization mode of the receiving beam may include, but is not limited to, a single polarization mode and a dual polarization mode, the single polarization mode may refer to only one polarization mode of the receiving beam, and may be vertical polarization or horizontal polarization, and the dual polarization mode may refer to two polarization modes of the receiving beam, such as: both horizontal and vertical polarizations may be included. The polarization mode of the receiving beam of the terminal device is an inherent characteristic of the terminal device, and the terminal device can acquire the polarization mode of the receiving beam from its own configuration without limitation. The corresponding relation between the polarization mode of the receiving beam and the compensation value of the CQI satisfies the following conditions: the absolute value of the compensation value of the CQI corresponding to the single polarization mode is greater than the absolute value of the compensation value of the CQI corresponding to the dual polarization mode, for example: compared with a single polarization mode, the dual polarization mode has high stability of receiving beams, the terminal equipment has high possibility of receiving and sending beams after rotating, channel change may not be too large, and the absolute value of the compensation value of the CQI can be smaller.

Illustratively, the terminal device obtains the compensation value of the CQI at least according to the rotation state information of the terminal device and the received beam parameter information, and the compensation value may include any one of the following three cases:

the first condition is as follows: and the terminal equipment determines a compensation value of the CQI at least according to the second corresponding relation, the rotation direction of the terminal equipment and the beam width of the receiving beam.

In this embodiment of the application, the second corresponding relationship may be a list-type corresponding relationship, or may be an array-type or other-type corresponding relationship, which is not limited. The embodiment of the present application is described only by taking the second correspondence as the correspondence in the form of a list as an example.

In case one, the second corresponding relationship may include a corresponding relationship between the rotation direction of the terminal device and the compensation value of the CQI, and the second corresponding relationship further includes a corresponding relationship between the beam width of the received beam and the compensation value of the CQI; alternatively, the correspondence between the rotation direction of the terminal device and the offset value of the CQI and the correspondence between the beam width of the reception beam and the offset value of the CQI are included in different correspondence lists, which is not limited.

Case two: and the terminal equipment determines the compensation value of the CQI at least according to the second corresponding relation, the rotation direction of the terminal equipment and the polarization mode of the receiving wave beam.

In case two, the second corresponding relationship may include a corresponding relationship between the rotation direction of the terminal device and the compensation value of the CQI, and the second corresponding relationship further includes a corresponding relationship between the polarization mode of the received beam and the compensation value of the CQI; alternatively, the correspondence between the rotation direction of the terminal device and the offset value of the CQI and the correspondence between the polarization of the received beam and the offset value of the CQI are included in different correspondence lists, which is not limited.

Case three: and the terminal equipment determines the compensation value of the CQI at least according to the second corresponding relation, the rotation direction of the terminal equipment, the beam width of the receiving beam and the polarization mode of the receiving beam.

In case three, the second corresponding relationship may include a corresponding relationship between the rotation direction of the terminal device and the compensation value of the CQI, and the second corresponding relationship further includes a corresponding relationship between the polarization mode of the received beam, the beam width of the received beam, and the compensation value of the CQI; alternatively, the correspondence between the rotation direction of the terminal device and the offset value of the CQI, the correspondence between the beam width of the reception beam and the offset value of the CQI, and the correspondence between the polarization mode of the reception beam and the offset value of the CQI are included in different correspondence lists, which is not limited.

For example, the compensation value of CQI is determined by the terminal device at least according to the second corresponding relationship, the rotation direction of the terminal device, and the polarization manner of the received beam, and the corresponding relationship between the rotation direction of the terminal device and the compensation value of CQI, and the corresponding relationship between the polarization manner of the received beam and the compensation value of CQI are included in different lists, such as: the correspondence between the rotation direction of the terminal device and the offset value of the CQI is shown in table two above, and the correspondence between the polarization mode of the received beam and the absolute value of the offset value of the CQI is shown in table four below as an example. As shown in table four, when the polarization method is single polarization, the absolute value of the CQI offset value is 2, and when the polarization method is dual polarization, the absolute value of the CQI offset value is 1, which is smaller than the absolute value of the CQI offset value corresponding to single polarization. With reference to table two and table four, when the terminal device is close to the beam center of the transmission beam and the polarization mode of the reception beam is single polarization, the offset value of the CQI may be determined to be 2, and when the terminal device is far from the beam center of the transmission beam and the polarization mode of the reception beam is single polarization, the offset value of the CQI may be determined to be-2.

For another example, if the correspondence relationship between the rotation direction of the terminal device and the offset value of the CQI and the correspondence relationship between the polarization of the reception beam and the offset value of the CQI are included in the same list, as shown in table five, for example, when the polarization of the reception beam is single polarization, the CQI offset value corresponding to the beam center at which the terminal device is close to the transmission beam is 2, and the CQI offset value corresponding to the beam center at which the terminal device is far from the transmission beam is-2.

Watch five

For another example, the terminal device determines the CQI offset value according to at least the second correspondence, the rotation direction of the terminal device, and the beam width of the received beam, and the correspondence between the rotation direction of the terminal device and the CQI offset value and the correspondence between the beam width of the received beam and the CQI offset value are included in different lists, such as: the correspondence between the rotation direction of the terminal device and the offset value of the CQI is shown in table two above, and the correspondence between the beam width of the reception beam and the absolute value of the offset value of the CQI is shown in table six below as an example. As shown in table six: as can be seen from table six, the absolute value of the CQI offset value is 1 when the beam width of the reception beam is 5 degrees, 2 when the beam width of the reception beam is 10 degrees, and 1.5 when the beam width of the reception beam is 15 degrees, and the absolute value of the CQI offset value is smaller as the beam width of the reception beam is wider, whereas the absolute value of the CQI offset value is larger as the beam width of the reception beam is narrower. With reference to table two and table six, when the terminal device is close to the beam center of the transmission beam and the beam width of the reception beam is 5 degrees, the offset value of the CQI may be determined to be 2, and when the terminal device is far from the beam center of the transmission beam and the beam width of the reception beam is 5 degrees, the offset value of the CQI may be determined to be-2.

Watch six

For another example, if the correspondence relationship between the rotation direction of the terminal device and the offset value of the CQI and the correspondence relationship between the beam width of the reception beam and the offset value of the CQI are included in the same list, for example, as shown in table seven, when the beam width of the reception beam is 10, the CQI offset value corresponding to the beam center of the terminal device close to the transmission beam is 1.5, and the offset value of the CQI corresponding to the beam center of the terminal device far from the transmission beam is-1.5.

Watch seven

It should be noted that, for the process of the terminal device determining the compensation value of the CQI at least according to the second corresponding relationship, the rotation direction of the terminal device, the beam width of the received beam, and the polarization mode of the received beam, reference may be made to the above example, and details are not repeated.

Therefore, the terminal equipment can determine the compensation value of the CQI according to the rotation direction of the terminal equipment, the polarization mode of the receiving beam and/or the beam width of the receiving beam, and adjust the measured CQI by using the determined compensation value of the CQI, so that the adjusted CQI can be suitable for the rotation condition of the terminal equipment, the channel quality of the transmission channel after the rotation of the terminal equipment is matched, and the network side is prevented from allocating too high or too low MCS to the terminal equipment. Meanwhile, the polarization mode of the received wave beam and/or the wave beam width of the received wave beam are inherent properties of the received wave beam, the polarization mode of the received wave beam and/or the wave beam width of the received wave beam can be obtained without calculation, the operation is simple, and the efficiency of determining the CQI compensation value is improved.

In a third scenario of the method shown in fig. 4, to avoid a problem that power consumption of a terminal device is too large due to the terminal device always starting to execute a function of CSI reporting according to the embodiment of the present application, before step 401 is executed, the terminal device determines whether a CSI reporting period is greater than a preset period; if the CSI reporting period is greater than the preset period, the terminal device is turned on to execute the function of the method shown in fig. 4, and the method shown in fig. 4 is executed, otherwise, the terminal device is turned off to execute the function of the method shown in fig. 4.

The preset period can be set according to needs, and is not limited. For example, the preset period may be set to about 40 ms. The CSI reporting period may refer to a time interval between two CSI reports by the terminal device, and the CSI reporting period may be configured to the terminal device by the access network device through a high-level signaling or a dynamic signaling.

If the CSI reporting period of the terminal equipment is greater than the preset period, the CSI reporting time interval of the terminal equipment is longer, and in the longer time interval, the terminal equipment is likely to move or rotate and other posture changes, and the CSI calculated by the terminal equipment needs to be adjusted; on the contrary, if the CSI reporting period of the terminal device is less than or equal to the preset period, it indicates that the time interval for reporting the CSI by the terminal device is short, and the CSI is reported by the terminal device frequently, and in this short time interval, even if the terminal device frequently changes in posture such as movement or rotation, the change of the channel can be tracked more accurately through frequent CSI measurement and reporting, and the terminal device does not need to adjust the CSI and start the function of performing the CSI reporting described in the embodiment of the present application.

In a fourth scenario of the method shown in fig. 4, if the terminal device does not rotate for a long time, for example: if no rotation occurs within the second time period, the terminal device may reset the accumulated compensation value obtained in step 403, such as: resetting the accumulated offset value to zero or other values, etc., without limitation.

Wherein, the second time period can be set according to the requirement, such as: the time period for reporting CSI for multiple consecutive times may be used as the second time period, which is not limited.

Therefore, the accumulated compensation value can be updated regularly, and the accuracy of adjusting the CQI by adopting the accumulated compensation value is ensured.
