[0145] 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."

[0154] 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.

[0155] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0156] 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 / or other components. 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] The user input unit 107 can be used to receive input digital or character information and generate key signal input related to 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 corresponding connected devices 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 and execute commands sent by the processor 110. And / or, 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.

[0163] 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.

[0182] Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are proposed.

[0183] Technical terms involved in this embodiment:

[0184] PRACH: Physical Random Access Channel, physical random access channel;

[0185] SBFD: Subband Full-Duplex, subband full-duplex;

[0186] non-SBFD: non-sub-band full-duplex;

[0187] FR1 / FR2 TDD: Frequency Range 1 / Frequency Range 2 Time Division Full Duplex;

[0188] TDD-DL-UL common: time division full duplex - downlink - uplink common;

[0189] RO: RACH Occasion, random access opportunity;

[0190] DL: Downlink, downlink;

[0191] FL: Flexible Slot, flexible time slot;

[0192] UL: Uplink, uplink;

[0193] TDD-UL-DL-ConfigurationCommon: time division full duplex - downlink - uplink - common configuration;

[0194] SS / PBCH: Synchronization Signal / PBCH, synchronization signal / physical broadcast channel;

[0195] CORESET: Control Resource Set, control resource set;

[0196] CSI-RS: Channel State Information Reference Signal, channel state information reference signal;

[0197] PDSCH: Physical Downlink Shared Channel, physical downlink shared channel.

[0198] This application takes into account that in existing protocols, the PRACH (Physical Random Access Control Channel) configuration table for random access procedures in FR1 / FR2 TDD (Frequency Range 1 / Frequency Range 2 Time Division Full Duplex) spectrum is designed for UL (Uplink) time slots in TDD. Therefore, the current PRACH configuration table for FR1 / FR2 TDD spectrum cannot flexibly configure random access opportunities in SBFD (Sub-Band Full Duplex) time slots indicated as DL symbols by TDD-DL-UL common (Time Division Full Duplex - Downlink-Uplink Common).

[0199] For example, considering random access in FR1 and TDD spectrum, to configure a long PRACH sequence based on format 0 and with a period of 20ms (every other frame), only the four PRACH configuration indices numbered 3-6 in Table 6.3.3.2-3 of protocol 38.211 can be used. In these possible configurations, the PRACH time slot can only be located in subframe index 4 or 9, as shown in Table 1 below. When these PRACH configurations are applied to the most commonly used time slot modes DDDSUDDSUU, it can be found that the PRACH time slot is only located in the two uplink time slots in subframe 4 or subframe 9, as shown in Table 2.

[0200] Table 1: PRACH configuration for FR1 unpaired spectrum

[0201] Table 2

[0202] In addition, another limitation of the TDD PRACH configuration table is that there is no PRACH configuration index that only allows RO (random access opportunity) to be enabled in subframe #0, which may be necessary to enable RO in the SBFD slot of the first or second DL slot configuration. The only PRACH configuration that enables RO in subframe #0 is based on all ROs in all subframes 0, 1, 2, ..., 9 (for example, row 86 in format A1 in Table 6.3.3.2-3).

[0203] In addition to PRACH configuration, the current specification limits the determination of valid RACH Occasions to UL slots and / or FL slots, and places certain conditions on whether the SSB precedes or follows the RACH Occasion. Given that current SBFD slots / symbols are DL or FL symbols, these rules do not allow verification of RACH Occasion validity in SBFD symbols, thus impacting network performance.

[0204] Based on the above considerations, the embodiments of the present application propose one or more technical solutions to solve the problem that the PRACH configuration table cannot flexibly configure random access timing in SBFD time slots, and / or solve the problem of valid RACH Occasion verification in SBFD time slots.
