[0002] In existing protocols, network equipment (such as base stations) sends CSI-RS to terminal devices (such as mobile phones). The terminal devices measure the CSI-RS and report CSI Reports to the network equipment.

[0070] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the term "if," as used herein, may be interpreted as "upon," "when," or "in response to a determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context indicates otherwise. It should be further understood that the terms "comprising" and "including" indicate the presence of the recited features, steps, operations, elements, components, items, types, and / or groups, but do not preclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, types, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used herein, may be interpreted as inclusive, meaning any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”; and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”.

When implementing the step, those skilled in the art may execute S2 first and then S1, etc., but these should all be within the scope of protection of this application.

[0074] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0075] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0076] The communication equipment mentioned in this application can be a terminal device (such as a mobile terminal, specifically a mobile phone) or a network device (such as a base station). The specific reference needs to be clarified in the context.

For example, the terminal device described in this application may include smart terminals such as mobile phones, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and fixed terminals such as digital TVs and desktop computers.

[0078] The subsequent description will be made by taking a mobile terminal as an example. It will be understood by those skilled in the art that, in addition to components specifically used for mobile purposes, the configuration according to the embodiments of the present application can also be applied to fixed-type terminals.

[0079] Please refer to Figure 1, which is a schematic diagram of the hardware structure of a mobile terminal for implementing various embodiments of the present application. The mobile terminal 100 may include components such as an RF (Radio Frequency) unit 101, a WiFi module 102, an audio output unit 103, an A / V (Audio / Video) input unit 104, a sensor 105, a display unit 106, a user input unit 107, an interface unit 108, a memory 109, a processor 110, and a power supply 111. Those skilled in the art will understand that the mobile terminal structure shown in Figure 1 does not limit the mobile terminal. The mobile terminal may include more or fewer components than shown, or may combine certain components, or arrange the components differently.

[0080] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0081] The RF unit 101 can be used to send and receive information or receive signals during calls. Specifically, it receives downlink information from the base station and transmits it to the processor 110 for processing. It also transmits uplink data to the base station. Typically, the RF unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, and more. Furthermore, the RF unit 101 can communicate with the network and other devices via wireless communication. The above-mentioned wireless communications can use any communication standard or protocol, including but not limited to GSM (Global System of Mobile communication), GPRS (General Packet Radio Service), CDMA2000 (Code Division Multiple Access 2000), WCDMA (Wideband Code Division Multiple Access), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), FDD-LTE (Frequency Division Duplexing-Long Term Evolution), TDD-LTE (Time Division Duplexing-Long Term Evolution), 5G and 6G, etc.

[0082] WiFi is a short-range wireless transmission technology. A mobile terminal, through WiFi module 102, enables users to send and receive emails, browse web pages, and access streaming media, providing wireless broadband Internet access. Although FIG1 illustrates WiFi module 102, it is understood that it is not a required component of the mobile terminal and can be omitted as needed without altering the essence of the invention.

[0083] The audio output unit 103 can convert audio data received by the RF unit 101 or the WiFi module 102 or stored in the memory 109 into an audio signal and output it as sound when the mobile terminal 100 is in a call signal reception mode, a talk mode, a recording mode, a voice recognition mode, a broadcast reception mode, or the like. Furthermore, the audio output unit 103 can also provide audio output related to a specific function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output unit 103 may include a speaker, a buzzer, or the like.

[0084] The A / V input unit 104 is used to receive audio or video signals. The A / V input unit 104 may include a graphics processing unit (GPU) 1041 and a microphone 1042. The GPU 1041 processes image data of still images or videos captured by an image capture device (e.g., a camera) in video capture mode or image capture mode. The processed image frames may be displayed on the display unit 106. The image frames processed by the GPU 1041 may be stored in the memory 109 (or other storage medium) or transmitted via the RF unit 101 or the WiFi module 102. The microphone 1042 may receive sound (audio data) in operating modes such as a phone call mode, a recording mode, and a voice recognition mode, and may process such sound into audio data. In the phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101. The microphone 1042 may implement various types of noise cancellation (or suppression) algorithms to eliminate (or suppress) noise or interference generated during the reception and transmission of audio signals.

[0085] The mobile terminal 100 also includes at least one sensor 105, such as a light sensor, a motion sensor, and other sensors. Optionally, the light sensor includes an ambient light sensor and a proximity sensor. Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the brightness of the ambient light, and the proximity sensor can turn off the display panel 1061 and / or the backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

[0086] The display unit 106 is used to display information input by the user or information provided to the user. The display unit 106 may include a display panel 1061, which may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), or the like.

[0087] The user input unit 107 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile terminal. Optionally, the user input unit 107 may include a touch panel 1071 and other input devices 1072. The touch panel 1071, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using a finger, stylus, or any other suitable object or accessory on or near the touch panel 1071) and drive the corresponding connection device according to a pre-set program. The touch panel 1071 may include two parts: a touch detection device and a touch controller. Optionally, the touch detection device detects the user's touch direction and detects the signal generated by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 110. It can also receive commands sent by the processor 110 and execute them. In addition, the touch panel 1071 can be implemented using various types such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 1071, the user input unit 107 may further include other input devices 1072. Optionally, the other input devices 1072 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power keys, etc.), a trackball, a mouse, a joystick, etc., and the specifics are not limited here.

[0088] Optionally, the touch panel 1071 may overlay the display panel 1061. When the touch panel 1071 detects a touch operation on or near it, it transmits the information to the processor 110 to determine the type of touch event. The processor 110 then provides a corresponding visual output on the display panel 1061 based on the type of touch event. Although in FIG1 , the touch panel 1071 and the display panel 1061 are shown as two separate components to implement the input and output functions of the mobile terminal, in some embodiments, the touch panel 1071 and the display panel 1061 may be integrated to implement the input and output functions of the mobile terminal, which is not limited to this specific embodiment.

[0089] The interface unit 108 serves as an interface through which at least one external device can be connected to the mobile terminal 100. For example, the external device may include a wired or wireless headset port, an external power supply (or battery charger) port, a wired or wireless data port, a memory card port, a port for connecting a device with an identification module, an audio input / output (I / O) port, a video I / O port, a headphone port, etc. The interface unit 108 may be used to receive input (e.g., data information, power, etc.) from an external device and transmit the received input to one or more elements within the mobile terminal 100 or may be used to transmit data between the mobile terminal 100 and an external device.

[0090] Memory 109 can be used to store software programs and various data. Memory 109 may primarily include a program storage area and a data storage area. Optionally, the program storage area may store an operating system and at least one application required for a function (such as a sound playback function or an image playback function); the data storage area may store data generated based on the use of the mobile phone (such as audio data, a phone book, etc.). Furthermore, memory 109 may include high-speed random access memory and non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0091] Processor 110 is the control center of the mobile terminal, connecting all components of the mobile terminal using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 109 and accessing data stored in memory 109, it executes various functions of the mobile terminal and processes data, thereby providing overall monitoring of the mobile terminal. Processor 110 may include one or more processing units; preferably, processor 110 may integrate an application processor and a modem processor. Optionally, the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 110.

[0092] The mobile terminal 100 may also include a power supply 111 (such as a battery) for supplying power to various components. Preferably, the power supply 111 may be logically connected to the processor 110 through a power management system, thereby enabling the power management system to manage functions such as charging, discharging, and power consumption.

[0219] The number of bits occupied by the antenna port number indication in a CSI Report is 8. The bits of the antenna port number indication bits correspond to the logical index numbers 0-7 in the logical index number column of the above table from high to low, respectively. The first preset rule is to determine the logical index numbers of each number of antenna ports to be measured according to the resource identifiers of the channel state information reference signal corresponding to the number of antenna ports to be measured, sorted from small to large. According to Table 3, the most significant bit on the left of the antenna port number indication bit corresponds to the logical index number 0, that is, the non-zero power channel state information reference signal resource identifier 0, the second bit on the left corresponds to the logical index number 1, that is, the non-zero power channel state information reference signal resource identifier 5, and so on.

Optionally, bit 000 represents that the channel state information of the best number of antenna ports needs to be reported, bit 001 represents that the channel state of the best number of antenna ports needs to be reported, bit 010 represents that the channel state of the best number of antenna ports needs to be reported..., bit 111 represents that the channel state of the best number of antenna ports needs to be reported.

[0254] If the preferred channel state information quantity indication field in the downlink control information is bits 011, and the number of antenna ports to be measured indicated in the downlink control information, the radio resource control information and / or the media access control information is 6, and the number of antenna ports to be measured includes: 32port, 16port, 12port, 8port, 4port, 2port. The terminal device first obtains the time-frequency domain resources of the non-zero power channel state information reference signal corresponding to each of the above 6 antenna ports to be measured based on the downlink control information, wireless resource control information and / or media access control information in the downlink information, and measures the non-zero power channel state information reference signal corresponding to each antenna port number, thereby obtaining the channel reception quality corresponding to each antenna port number. Then, the terminal device sorts the channel reception quality of each antenna port number in descending order. For example, the sorting results of the antenna port numbers corresponding to the channel reception quality from high to low are: 16port, 8port, 4port, 2port, 12port, 32port. Since the preferred channel state information number indication field bits 011 in the downlink control information are simultaneously combined, the number of CSIs that need to be included in a CSI Report is 3, that is, the number of antenna ports corresponding to the 3 CSIs that need to be reported are 16port, 8port, and 4port, respectively.

[0255] Optionally, the number of bits occupied by the antenna port number indication in a CSI Report is 64. Optionally, the antenna port number indication bits correspond to non-zero power channel state information reference signal resource set identifiers 0 to 63 from high to low, and the three antenna port numbers 16port, 8port, and 4port that need to be reported correspond to non-zero power channel state information reference signal resource set identifiers 1, 3, and 60, respectively. The terminal device determines that the UCI bit of the antenna port number indication corresponding to the number of antenna ports reported in the CSI Report is 0101 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 1000.

[0256] Optionally, the antenna port number indication may be a logical index number related to a resource set identifier of a channel state information reference signal corresponding to a set of antenna port numbers to be measured and / or a number of antenna ports to be measured that meets a first preset rule.

[0257] Optionally, satisfying the first preset rule includes at least one of the following:

[0258] Determine the logical index number of each antenna port number to be measured according to the order of the number of antenna ports to be measured from large to small;

[0259] Determine the logical index number of each antenna port number to be measured according to the order of the number of antenna ports to be measured from small to large;

[0260] Determine the logical index number of each antenna port number to be measured by sorting the CSI-RS resource set identifiers corresponding to the number of antenna ports to be measured from small to large;

[0261] The logical index numbers of the numbers of antenna ports to be measured are determined by sorting the CSI-RS resource set identifiers corresponding to the numbers of antenna ports to be measured from large to small.

[0262] Optionally, the first preset rule is to determine the logical index number of each number of antenna ports to be measured in descending order according to the number of antenna ports to be measured. The logical index number of each number of antenna ports to be measured determined according to the first preset rule is shown in Table 5:

[0263] Table 5

[0264] The number of bits occupied by the antenna port number indication in a CSI Report is 8. The bits of the antenna port number indication bits correspond to the logical index numbers 0-7 in the logical index number column in the above table from high to low, respectively. The first preset rule is to determine the logical index numbers of the number of antenna ports to be measured in descending order according to the number of antenna ports to be measured. According to Table 5, the most significant bit on the left of the antenna port number indication bit corresponds to the logical index number 0, that is, the number of antenna ports is 32, the second bit on the left corresponds to the logical index number 1, that is, the number of antenna ports is 24, and so on. Therefore, when the channel state information reference signals with different numbers of antenna ports have different non-zero power channel state information reference signal resource set identifiers, and the three antenna port numbers that the terminal device needs to report are 16 ports, 8 ports, and 4 ports respectively, the number of antenna ports in a CSI report is indicated as bits 00101100.

[0265] Optionally, the first preset rule is satisfied by determining the logical index number of each number of antenna ports to be measured in ascending order according to the number of antenna ports to be measured. The logical index number of each number of antenna ports to be measured determined according to satisfying the first preset rule is shown in Table 6:

[0266] Table 6

[0267] The number of bits occupied by the antenna port number indication in a CSI Report is 8. The bits of the antenna port number indication bits correspond to the logical index numbers 0-7 in the logical index number column of the above table from high to low, respectively. The first preset rule is to determine the logical index numbers of the number of antenna ports to be measured in ascending order according to the number of antenna ports to be measured. According to Table 6, the most significant bit on the left of the antenna port number indication bit corresponds to the logical index number 0, that is, the number of antenna ports 1, the second bit on the left corresponds to the logical index number 1, that is, the number of antenna ports 2, and so on. Therefore, when the channel state information reference signals with different numbers of antenna ports have different non-zero power channel state information reference signal resource set identifiers, and the terminal device needs to report 3 antenna port numbers 16port, 8port, and 4port, the number of antenna ports in a CSI report is indicated as bits 00110100.

[0268] Optionally, the first preset rule is satisfied by determining the logical index number of each number of antenna ports to be measured by sorting the resource set identifiers of the CSI-RS corresponding to the number of antenna ports to be measured from small to large. The logical index number of each number of antenna ports to be measured determined based on satisfying the first preset rule is shown in Table 7:

[0269] Table 7

[0270] The number of bits occupied by the antenna port number indication in a CSI Report is 8. The bits of the antenna port number indication bits correspond to the logical index numbers 0-7 in the logical index number column of the above table from high to low, respectively. The first preset rule is to determine the logical index numbers of the number of antenna ports to be measured according to the resource set identifiers of the channel state information reference signal corresponding to the number of antenna ports to be measured, sorted from small to large. According to Table 7, the leftmost bit of the antenna port number indication bit corresponds to the logical index number 0, that is, the non-zero power channel state information reference signal resource set identifier 0, the second bit from the left corresponds to the logical index number 1, that is, the non-zero power channel state information reference signal resource set identifier 5, and so on. Therefore, when the channel state information reference signals with different numbers of antenna ports have different non-zero power channel state information reference signal resource set identifiers, and the three antenna port numbers 16port, 8port, and 4port that the terminal device needs to report correspond to the non-zero power channel state information reference signal resource set identifiers of 12, 8, and 28, respectively, the number of antenna ports in a CSI report is indicated as bits 00101001.

[0271] Optionally, the first preset rule is satisfied by determining the logical index number of each number of antenna ports to be measured by sorting the resource set identifiers of the CSI-RS corresponding to the number of antenna ports to be measured from large to small. The logical index number of each number of antenna ports to be measured determined based on satisfying the first preset rule is shown in Table 8:

[0272] Table 8

[0273] The number of bits occupied by the antenna port number indication in a CSI Report is 8. The bits of the antenna port number indication bits correspond to the logical index numbers 0-7 in the logical index number column of the above table from high to low, respectively. The first preset rule is to determine the logical index numbers of each number of antenna ports to be measured according to the resource set identifiers of the channel state information reference signal corresponding to the number of antenna ports to be measured, sorted from large to small. According to Table 8, the most significant bit on the left of the antenna port number indication bit corresponds to the logical index number 0, that is, the non-zero power channel state information reference signal resource set identifier 28, the second bit on the left corresponds to the logical index number 1, that is, the non-zero power channel state information reference signal resource set identifier 25, and so on. Therefore, when the channel state information reference signals with different numbers of antenna ports have different non-zero power channel state information reference signal resource set identifiers, and the terminal device determines that the non-zero power channel state information reference signal resource set identifiers corresponding to the three antenna port numbers 16port, 8port, and 4port to be reported are 12, 8, and 28, respectively, the number of antenna ports indicated in a CSI report is bits 10010100.

[0274] Optionally, the non-zero power channel state information reference signal resource set identifiers corresponding to the number of antenna ports in Tables 5 to 8 are only examples. In practice, the non-zero power channel state information reference signal resource set identifiers corresponding to the number of antenna ports configured by the wireless resource control information in the system shall prevail.

[0275] Optionally, the antenna port number indication may be a logical index number for the N antenna port numbers that satisfy a first preset rule. Optionally, a CSI Report also includes N CSIs corresponding to N different antenna port numbers. The terminal device places the bits consisting of the wideband channel quality indication and / or rank indication corresponding to at least one of the first N antenna port numbers in the ranking together with the bits indicating the number of antenna ports in the same CSI report and reports them to the network device.

[0276] In the technical solution of this embodiment: the network device sends downlink control information, and the terminal device selects or determines the number N of CSIs contained in a CSI Report based on the indication field of the number of preferred channel state information in the downlink control information; the terminal device determines the channel reception quality of each number of antenna ports to be measured, and the antenna port number indication corresponding to the number of antenna ports with the best channel reception quality of the first N antenna ports, the broadband channel quality indication or rank indication of at least one antenna port number among the first N antenna ports with the best channel reception quality, and the antenna port number indication constitute the UCI bit, and report it to the network device through a CSI Report to achieve the purpose of reducing the number of CSI reports and / or ensuring the timeliness of CSI; and in the technical solution of this embodiment, the number of bits occupied by the antenna port number indication is effectively reduced by reporting the logical index number of each antenna port number, thereby further reducing the overhead of the CSI report; at the same time, the number of antenna ports corresponding to the reported N CSIs is determined according to the antenna port number indication, so that the network device can quickly identify the current CSI The values ​​of the number of antenna ports corresponding to the multiple CSI results in the report facilitate the network equipment to determine the transmission parameters of the physical downlink shared channel transmission, such as the number of antenna ports available for PDSCH transmission.

[0303] Optionally, the value of the number N of preferred antenna ports that need to be reported determined by the terminal device can be determined according to the current uplink service demand of the terminal device. For example, if the amount of data that the terminal device currently needs to transmit for uplink service is relatively large, then the number N of antenna ports that the terminal device selects to be reported can be relatively small, which is used to reduce the overhead of the uplink CSI report to reserve more uplink resources for uplink service transmission; if the amount of data transmitted for uplink service is greater than the second threshold, then the number N of antenna ports that the terminal device selects to be reported is 2 or 3 or other values; if the amount of data transmitted for uplink service is less than the second threshold, then the number N of antenna ports that the terminal selects to be reported is 5 or 6 or other values.
