Description

Technical Field

[0001] This application relates to the field of communication technology, specifically to a monitoring method, communication device, and storage medium. Background Technology

[0002] In the existing protocol, after the terminal device sends the first message (copy) (such as Msg3) within the transmission window, it needs to start a listening window after the transmission window ends (or after adding the round-trip time (RTT) from the terminal device to the network device) to listen for the PDCCH (Physical Downlink Control Channel) scrambled by RNTI (Radio-Network Temporary Identifier) ​​and receive the corresponding response message (such as Msg4).

[0003] In the process of conceiving and implementing this application, the inventors discovered at least the following problems:

[0004] Because terminal devices sending the first message (copy) within the same transmission window need to listen to the same RNTI-scrambled PDCCH, and the corresponding response message may carry response messages from multiple terminal devices, the terminal device needs to continuously listen to the PDCCH and / or parse response messages from all other scheduled terminal devices until it receives a matching response message or the listening window times out. This increases the power consumption of the terminal device. Therefore, it is necessary to optimize the listening mechanism to reduce the power consumption of the terminal device.

Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element, and / or, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0083] 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 only to distinguish information of the same type from one another. For example, without departing from the scope of this document, 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 word "if," as used herein, may be interpreted as "when," "when," or "in response to determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms "comprising," "including," indicate the presence of the stated feature, step, operation, element, component, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms "or," "and / or," "including at least one of the following," etc., as used in this application, may be interpreted as inclusive, or mean any one or any combination thereof. For example, "including at least one of the following: A, B, C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Similarly, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A and B and C." Exceptions to this definition only occur when the combination of elements, functions, steps, or operations is inherently mutually exclusive in some way.

[0084] It should be understood that although the steps in the flowcharts of this application's embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows.

[0086] It should be noted that step designations such as S1 and S2 are used in this document for the purpose of more clearly and concisely describing the corresponding content, and do not constitute a substantial limitation on the order. In specific implementation, those skilled in the art may execute S2 first and then S1, etc., but these should all be within the protection scope of this application.

[0087] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0088] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0089] The communication equipment mentioned in this application may be a terminal device (such as a mobile phone), a network device (such as a base station), or a chip (such as a SOC or a baseband chip with communication functions).

[0093] Please see Figure 1 This is a schematic diagram of the hardware structure of a mobile terminal implementing various embodiments of this application. The mobile terminal 100 may include: a 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, etc. Those skilled in the art will understand that... Figure 1The mobile terminal structure shown does not constitute a limitation on the mobile terminal. The mobile terminal may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0094] The following is combined with Figure 1 A detailed introduction to each component of the mobile terminal:

[0095] The radio frequency unit 101 can be used for receiving and transmitting signals during information transmission or calls. Specifically, it receives downlink information from the base station and processes it with the processor 110; additionally, it transmits uplink data to the base station. Typically, the radio frequency unit 101 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low-noise amplifier, a duplexer, etc. And / or, the radio frequency unit 101 can also communicate wirelessly with networks and other devices.

[0096] WiFi is a short-range wireless transmission technology. Mobile terminals, through the WiFi module 102, can help users send and receive emails, browse web pages, and access streaming media, providing users with wireless broadband internet access. Although Figure 1 WiFi module 102 is shown, but it is understood that it is not a necessary component of a mobile terminal and can be omitted as needed without changing the nature of the invention.

[0097] The audio output unit 103 can convert audio data received by the radio frequency unit 101 or the WiFi module 102 or stored in the memory 109 into audio signals and output them as sound when the mobile terminal 100 is in call signal receiving mode, call mode, recording mode, voice recognition mode, broadcast receiving mode, or other modes. Furthermore, the audio output unit 103 can also provide audio output related to specific functions performed by the mobile terminal 100 (e.g., call signal receiving sound, message receiving sound, etc.). The audio output unit 103 may include a speaker, a buzzer, etc.

The GPU 1041 processes image data of still images or videos acquired by an image capture device (such as a camera) in video capture mode or image capture mode. The processed image frames can be displayed on the display unit 106. The image frames processed by the GPU 1041 can be stored in the memory 109 (or other storage medium) or transmitted via the radio frequency unit 101 or the WiFi module 102. The microphone 1042 can receive sound (audio data) in operating modes such as telephone call mode, recording mode, and voice recognition mode, and can process such sound into audio data. The processed audio (voice) data can be converted into a format that can be transmitted to a mobile communication base station via the radio frequency unit 101 in telephone call mode. The microphone 1042 can 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.

Optionally, the ambient light sensor can adjust the brightness of the display panel 1061 according to the ambient light level, and the proximity sensor can turn off the display panel 1061 and / or backlight when the mobile terminal 100 is moved to the ear. As a type of motion sensor, an accelerometer sensor can detect the magnitude of acceleration in various directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that recognize the phone's posture (such as landscape / portrait switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc. Other sensors that may be configured in the phone, such as fingerprint sensors, pressure sensors, iris sensors, molecular sensors, gyroscopes, barometers, hygrometers, thermometers, and infrared sensors, will not be described in detail here.

Optionally, user input unit 107 may include touch panel 1071 and other input devices 1072. Touch panel 1071, also known as touch screen, can collect touch operations on or near the user (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near touch panel 1071), and drive corresponding connection devices according to a pre-set program. Touch panel 1071 may include two parts: touch detection device and touch controller. Optionally, touch detection device detects the user's touch position and the signal generated by the touch operation, and transmits the signal to touch controller; touch controller receives touch information from touch detection device, converts it into touch point coordinates, sends it to processor 110, and can receive and execute commands from processor 110. And / or, 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 also include other input devices 1072.

Although in Figure 1 In this embodiment, the touch panel 1071 and the display panel 1061 are two independent components to realize the input and output functions of the mobile terminal. However, in some embodiments, the touch panel 1071 and the display panel 1061 can be integrated to realize the input and output functions of the mobile terminal. The specific implementation is not limited here.

And / or, the memory 109 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0105] The processor 110 is the control center of the mobile terminal. It connects various parts of the mobile terminal via various interfaces and lines. By running or executing software programs and / or modules stored in the memory 109, and by calling data stored in the memory 109, it performs various functions and processes data of the mobile terminal, thereby providing overall monitoring of the mobile terminal. The processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor and a modem processor. Optionally, the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication.

[0137] First Embodiment

[0138] Reference Figure 5 , Figure 5 This is a flowchart illustrating the monitoring method of the first embodiment of this application. The monitoring method of this embodiment can be applied to a terminal device (such as a mobile phone) and includes the following steps:

[0139] S2: The terminal device stops the first listening window in response to the first condition being met.

[0140] This application embodiment takes into account that: since terminal devices sending the first message (copy) within the same transmission window need to listen to the same RNTI scrambled PDCCH, and the corresponding response message may carry response messages from multiple terminal devices, the terminal device needs to continuously listen to the PDCCH and / or parse the response messages of all other scheduled terminal devices before receiving a matching response message or before the listening window times out, which will increase the power consumption of the terminal device.

[0141] Therefore, this embodiment proposes a technical solution in which the terminal device stops the first listening window in response to the first condition, thereby optimizing the listening mechanism, reducing the terminal device's listening to the PDCCH, and thus reducing the power consumption of the terminal device.

[0142] Optionally, the network device sends first control information, and the terminal device responds by stopping the first listening window when the first condition is met.

[0143] Alternatively, network equipment may be base stations, etc.

[0164] Optionally, the terminal device may start a first listening window after the first transmission window ends.

[0165] Optionally, the terminal device starts the first listening window after the first transmission window ends and the first delay occurs.

[0166] Optionally, the first delay includes the round-trip time (RTT) from the terminal device to the network device and / or a fixed delay (such as processing time).

[0167] Optionally, the terminal device listens to the first RNTI-scrambled PDCCH within the first listening window.

[0168] Optionally, the first RNTI is determined or generated based on the first transmission window.

[0169] Optionally, when the terminal device detects the PDCCH scrambled by the first RNTI, it performs corresponding processing based on the information carried by the first control information. Optionally, the first control information carries at least one of the following: first indication information, second indication information, scheduling information corresponding to the first response information of the first message, and backoff indication.

[0170] Optionally, if the first indication information indicates that the first response message contains response information corresponding to the PUSCH timing or the group to which the PUSCH timing belongs or the PUSCH resource or the group to which the PUSCH resource belongs selected by the terminal device, then the terminal device parses the first response message according to the scheduling information.

[0172] Optionally, if the terminal device successfully parses the first response message and the first response message carries a contention resolution identifier that matches the terminal device, then the terminal device stops the first listening window. Optionally, at this time, it can be considered that the terminal device has successfully resolved the contention.

[0173] Optionally, if the terminal device successfully parses the first response message but the first response message does not carry a contention resolution identifier that matches the terminal device, and the first listening window has not timed out, then the terminal device continues to listen to the PDCCH scrambled by the first RNTI.

[0174] Optionally, if the terminal device successfully parses the first response message but the first response message carries a rollback indication, the terminal device stops the first listening window.

[0175] Optionally, the backoff indicator can be a fallback indicator or a backoff indicator.

[0176] Optionally, if the terminal device successfully parses the first response message but the first response message carries a stop indication, the terminal device stops the first listening window.

[0178] Optionally, the response information of the terminal device that sends the first message copy within the same PUSCH timing group or PUSCH resource group in the first transmission window can be carried in the same response message. By indicating whether there is response information corresponding to the corresponding group in the response message, the size of the indication information can be reduced.

[0179] Optionally, if the first indication information indicates that there is no response information in the first response message corresponding to the PUSCH timing or the packet to which the PUSCH timing belongs or the PUSCH resource or the packet to which the PUSCH resource belongs selected by the terminal device, and the first listening window has not expired, then the terminal device stops the first listening window (the network device may indicate that there is no response information for the current or subsequent PUSCH timing or PUSCH resource).

[0180] Optionally, if the first control information indicates that there is no first response message corresponding to the first transmission window and / or the first control information does not indicate or carry scheduling information of the first response message and / or the first control information carries a fallback indication, then the terminal device stops the first listening window.

[0182] Optionally, the second indication information indicates whether there is a first response message corresponding to the first transmission window.

[0183] Optionally, the scheduling information and / or fallback indication of the first response message may be indicated or carried by the second indication information.

[0184] Optionally, the second indication information uses the same fields as the first indication information. For example, the first indication information indicates that there is no corresponding response information for all PUSCH timings, PUSCH timing packets, PUSCH resources, or PUSCH resource packets within the first transmission window.

[0185] Optionally, the network device has demodulation information for each PUSCH resource (such as PUSCH time-frequency domain resources) within the first transmission window. When the network device no longer sends response messages for the first message (copy) (for example, all response messages have been sent or all PUSCH resources have failed to demodulate), the PDCCH listening window of some terminal devices may still not stop or time out. The network device instructs the terminal devices to stop the PDCCH listening window by sending indication information (such as first indication information, second indication information, etc.), thereby preventing the terminal devices from continuing to listen to the PDCCH scrambled by the first RNTI, which helps the terminal devices save power.

[0326] Optionally, if the terminal device successfully parses the first response message and the first response message carries a contention resolution identifier that matches the terminal device, then the terminal device stops the first listening window. Optionally, at this time, it can be considered that the terminal device has successfully resolved the contention.

When the network device no longer sends response messages for the first message (copy) (for example, all response messages have been sent or all PUSCH resources have failed to demodulate), the PDCCH listening window of some terminal devices may still not stop or time out. The network device instructs the terminal devices to stop the PDCCH listening window by sending indication information (such as first indication information, second indication information, etc.), thereby preventing the terminal devices from continuing to listen to the PDCCH scrambled by the first RNTI, which helps the terminal devices save power.

[0340] The technical solution of this embodiment can optimize the listening mechanism of the terminal device, reduce the terminal device's listening to the PDCCH, and thus reduce the power consumption of the terminal device.
