The configuration of the PDCCH monitoring period cannot be dynamically adjusted, which is obviously disadvantageous for power saving of the terminal device.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In order to provide a larger data transmission rate and improve user experience, a 5G next generation mobile communication system (New radio, NR) further increases the system bandwidth on the basis of 4G. In 5G NR, the maximum bandwidth supported by a single carrier is 100MHz for a frequency band below 6 GHz; for the frequency band above 6GHz, the maximum bandwidth supported by a single carrier is 400MHz.

For a large carrier bandwidth, such as 100MHz, the bandwidth that the terminal device needs to use is often very limited, and if the terminal device is made to detect and measure the whole bandwidth all the time, it will bring a great challenge to the power consumption of the terminal device, which is not favorable for power saving of the terminal device. Therefore, the concept of Bandwidth-width Part (BWP) is introduced in the 5G NR, that is, a Part of continuous Bandwidth is divided in the whole large Bandwidth carrier to transmit and receive data to and from the terminal device. The terminal device only needs to perform relevant operations in the part of the bandwidth configured by the network device, thereby achieving the effect of saving energy of the terminal device.

Based on the 5G NR Rel-15 standard, for each serving cell of the terminal device, a Radio Resource Control (RRC) network device may configure one or more BWPs for the terminal device on this serving cell, and the configurable maximum number of BWPs is 4. At each time, the terminal device only has 1 activated Downlink (DL) BWP and 1 activated Uplink (UL) BWP in the serving cell, and the terminal device can only perform data transceiving on the activated BWP. BWP handover can be achieved using the following 4 ways:

(1) BWP handover based on a Physical Downlink Control Channel (PDCCH);

(2) BWP handover based on RRC (re) configuration;

(3) BWP handover based on timer (timer) timeout;

(4) Random access initialization induced BWP handover.

The terminal equipment acquires the downlink or uplink scheduling information by receiving the PDCCH sent by the network equipment, thereby further completing the receiving and sending of the service data. The time when the network device schedules the terminal device is not fixed, and because no relevant signaling is notified to the terminal device, whether the network device sends the PDCCH to the terminal device or not is determined, and the terminal device needs to perform blind detection on the PDCCH. In order to reduce the complexity of blind detection of the terminal device, the set of blind detection PDCCHs needs to be limited. Therefore, the concept of a search space, i.e. a set of PDCCH resources that the terminal device needs to detect blindly, is introduced.

5G NR PDCCH configuration: a User Equipment (UE) monitors a PDCCH in a PDCCH search space configured by a network device. The network device may configure up to 10 PDCCH Search spaces for each DL BWP of the UE, where each PDCCH Search Space corresponds to one PDCCH monitoring period and is indexed by a Search Space (Search Space) Identity (Identity, id). Each PDCCH search space is associated with a Control Resource Set (Control Resource Set), each Control Resource Set corresponds to a frequency domain position, and each Control Resource Set is indexed by a Control Resource Set Id. The network device may configure up to 3 Control Resource sets for each DL BWP of the UE.

However, in the conventional Physical Downlink Control Channel (PDCCH) configuration, a PDCCH search space is configured semi-statically by Radio Resource Control (RRC). Due to the diversity and continuous variation of the terminal device services, the semi-static PDCCH search space configuration may not always be able to match the varying service characteristics and scheduling intervals well. For example, a PDCCH search space configured by the network device for the terminal device corresponds to a smaller PDCCH search period, the terminal device currently initiates a service, and the packet transmission interval of the service is larger. The configuration of the PDCCH monitoring period cannot be dynamically adjusted, which is obviously not favorable for saving power of the terminal device.

The following describes each component of the mobile phone in detail with reference to fig. 10:

RF circuit 1010 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, for processing downlink information of a base station after receiving the downlink information to processor 1080; in addition, the data for designing uplink is transmitted to the base station. In general, RF circuit 1010 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 1010 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to global system for mobile communication (GSM), general Packet Radio Service (GPRS), code Division Multiple Access (CDMA), wideband Code Division Multiple Access (WCDMA), long Term Evolution (LTE), email, short Message Service (SMS), etc.

The memory 1020 can be used for storing software programs and modules, and the processor 1080 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 1020. The memory 1020 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 1020 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 1030 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 1030 may include a touch panel 1031 and other input devices 1032. The touch panel 1031, also referred to as a touch screen, may collect touch operations by a user (e.g., operations by a user on or near the touch panel 1031 using any suitable object or accessory such as a finger, a stylus, etc.) and drive corresponding connection devices according to a preset program. Optionally, the touch panel 1031 may include two parts, namely a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 1080, and can receive and execute commands sent by the processor 1080. In addition, the touch panel 1031 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 1030 may include other input devices 1032 in addition to the touch panel 1031. In particular, other input devices 1032 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a track ball, a mouse, a joystick, or the like.

The display unit 1040 may be used to display information input by a user or information provided to the user and various menus of the cellular phone. The display unit 1040 may include a display panel 1041, and optionally, the display panel 1041 may be configured in the form of a Liquid Crystal Display (LCD), an organic light-Emitting diode (OLED), or the like. Further, the touch panel 1031 can cover the display panel 1041, and when the touch panel 1031 detects a touch operation on or near the touch panel 1031, the touch operation is transmitted to the processor 1080 to determine the type of the touch event, and then the processor 1080 provides a corresponding visual output on the display panel 1041 according to the type of the touch event. Although in fig. 10, the touch panel 1031 and the display panel 1041 are two separate components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 1031 and the display panel 1041 may be integrated to implement the input and output functions of the mobile phone.

The handset may also include at least one sensor 1050, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 1041 according to the brightness of ambient light, and the proximity sensor may turn off the display panel 1041 and/or the backlight when the mobile phone moves to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing gestures of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometers and taps), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuitry 1060, speaker 1061, microphone 1062 may provide an audio interface between the user and the handset. The audio circuit 1060 can transmit the electrical signal converted from the received audio data to the speaker 1061, and the electrical signal is converted into a sound signal by the speaker 1061 and output; on the other hand, the microphone 1062 converts the collected sound signal into an electrical signal, which is received by the audio circuit 1060 and converted into audio data, which is then processed by the audio data output processor 1080 and then sent to, for example, another cellular phone via the RF circuit 1010, or output to the memory 1020 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help the user to send and receive e-mail, browse web pages, access streaming media, etc. through the WiFi module 1070, which provides wireless broadband internet access for the user. Although fig. 10 shows the WiFi module 1070, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 1080 is a control center of the mobile phone, connects various parts of the whole mobile phone by using various interfaces and lines, and executes various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 1020 and calling data stored in the memory 1020, thereby integrally monitoring the mobile phone. Optionally, processor 1080 may include one or more processing units; preferably, the processor 1080 may integrate an application processor, which handles primarily the operating system, user interfaces, applications, etc., and a modem processor, which handles primarily the wireless communications. It is to be appreciated that the modem processor described above may not be integrated into processor 1080.

The handset also includes a power source 1090 (e.g., a battery) for powering the various components, which may preferably be logically coupled to the processor 1080 via a power management system to manage charging, discharging, and power consumption via the power management system. Although not shown, the mobile phone may further include a camera, a bluetooth module, etc., which are not described herein.
