[0001] The present application relates to the field of communication technology, and in particular to a processing method, communication equipment, and storage medium. Background Art

[0002] In existing protocols, PRACH (Physical Random Access CHannel) is an uplink physical channel in a communication system, mainly used by terminal devices to send random access requests to network devices to establish wireless connections or ensure uplink synchronization.

[0003] During the process of conceiving and implementing this application, the inventors discovered that there are at least the following problems: Since PRACH transmission is a periodic transmission channel, when there is no terminal device service, the network device does not know whether there is a terminal device performing random access. Therefore, it is necessary to periodically perform preamble code detection at the specified random access time, which will bring unnecessary signaling interaction and / or increase network energy consumption.

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.

[0125] The following is a detailed introduction to the various components of the mobile terminal in conjunction with Figure 1:

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

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.

[0133] 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.

[0135] 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, / or, 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.

[0136] 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.

[0260] Fourth embodiment

[0262] Optionally, determining the first random access configuration based on the wireless resource control information includes: obtaining the time domain and frequency domain positions of the random access opportunity based on the random access configuration index (prach-ConfigurationIndex) field in the wireless resource control information and Table 6.3.3.2-2, Table 6.3.3.2-3 and Table 6.3.3.2-4 in protocol 38.211.

[0263] Optionally, the random access configuration period is determined by a random access configuration index (prach-ConfigurationIndex) field in the radio resource control information.

[0264] Optionally, for FR1 and FDD, Table 6.3.3.2-2 in protocol 38.211 is used to determine the random access configuration period. Assuming that the prach-ConfigurationIndex value in the radio resource control information is 9, it can be known from the protocol that the terminal device is in n SFN mod4=1 system frame (x=4, y=0. That is, n SFN The preamble of format 0 is transmitted on subframe 4 of a system frame (system frame with mod4=1, 5, 9, ...). Therefore, the random access configuration period determined according to the random access configuration index field in the radio resource control information is 40ms.

[0265] Optionally, all random access opportunities within a random access configuration period in the first random access configuration are enabled or disabled based on a random access request field in the downlink control information. Optionally, the downlink control information is within a random access configuration period that is enabled as indicated by the downlink control information. For example, assume that there are 32 random access opportunities within a random access configuration period determined by the first random access configuration. Assume that the value of the random access request field in the downlink control information included in the random access configuration period is 1, then all 32 random access opportunities within the random access configuration period are enabled.

[0266] Optionally, all random access opportunities within a random access association period in the first random access configuration are enabled or disabled based on a random access request field in the downlink control information. Optionally, the downlink control information is located in a first random access configuration period corresponding to a random access association period enabled by the downlink control information. For example, assume that there are 32 random access opportunities within a random access association period determined by the first random access configuration. Assume that the value of the random access request field in the downlink control information corresponding to the random access association period is 1, then all 32 random access opportunities within the random access association period are enabled.

[0267] Optionally, one random access opportunity may be associated with one or more SSBs.

[0268] Optionally, the random access association period is to complete one N Tx SSB The minimum number of random access configuration cycles required for mapping SSBs to one random access opportunity once, and the value of the random access association period meets Table 1:

[0269] Table 1. Example of mapping between random access configuration period and associated period of synchronization signal block to random access opportunity mapping

[0270] Optionally, N Tx SSBDetermined by the synchronization signal block burst position (ssb-PositionsInBurst) field in the radio resource control information.

[0271] 8, FIG8 is a schematic diagram of a first example according to the fourth embodiment, assuming that the ssb-PositionsInBurst field in the radio resource control information is "11111111", therefore, the number of synchronization signal blocks N actually transmitted within 5ms Tx SSB = 8, and the transmitted synchronization signal block index is {0, 1, 2, 3, 4, 5, 6, 7}. Assume that the value of the ssb-perRACH-OccasionAndCB-PreamblesPerSSB field in the radio resource control information is 1 / 4. Therefore, one SSB is associated with four consecutive random access opportunities. Assume that the value of the msg1-FDM field in the radio resource control information is 4. Therefore, the number of frequency-domain random access opportunities in one random access configuration period is 4. Furthermore, if the number of time-domain random access opportunities in one random access configuration period is 4, then the number of random access opportunities in one random access configuration period is 4 (number of frequency-domain random access opportunities) * 4 (number of frequency-domain random access opportunities) = 16. Based on the above assumptions, the number of random access opportunities required to complete a complete SSB mapping is 8 (number of SSBs) * 4 (number of random access opportunities associated with one SSB) = 32. Therefore, one random access association period contains two random access configuration periods. FIG8 is a mapping diagram of the association relationship between SSB and RO.

[0272] Optionally, according to the random access request field in the downlink control information, enabling or disabling all random access opportunities within the random access configuration period or the random access association period in the first random access configuration may be applicable only to terminal devices in a service cell that supports network energy saving.

[0273] Optionally, under the first trigger event, the terminal device sends msg1 and / or msgA at a random access opportunity in a random access configuration period enabled by the random access request field in the downlink control information.

[0274] Optionally, under the first trigger event, the terminal device sends msg1 and / or msgA at a random access opportunity in a random access association period enabled by the random access request field in the downlink control information.

[0275] Optionally, the first trigger event may be specifically described in the third embodiment, which will not be described in detail in this embodiment.

[0276] Optionally, all random access opportunities within a random access configuration period in the first random access configuration are enabled or disabled according to a random access request field in the downlink control information. Optionally, the downlink control information is located within a random access configuration period indicated to be enabled or disabled by the downlink control information.

[0277] Referring to FIG9 , FIG9 is a schematic diagram illustrating a second example according to the fourth embodiment. As shown in FIG9 , all random access opportunities within a random access configuration period in a first random access configuration are enabled or disabled based on the random access request field in the downlink control information. When the value of the random access request field in the downlink control information is 1, all random access opportunities within the random access configuration period in which the downlink control information exists are enabled; when the value of the random access request field in the downlink control information is 0, all random access opportunities within the random access configuration period in which the downlink control information exists are disabled; and when no downlink control information containing the random access request field is received, all random access opportunities within the random access configuration period in which the downlink control information exists are disabled by default.

[0278] Optionally, all random access opportunities within a random access association period in the first random access configuration are enabled or disabled according to a random access request field in the downlink control information. Optionally, the downlink control information is located in a first random access configuration period corresponding to a random access association period enabled by the downlink control information.

[0279] 10 , which is a schematic diagram of a third example according to the fourth embodiment, as shown in FIG10 ,

[0280] All random access opportunities within a random access association period are enabled or disabled based on the random access request field in the downlink control information. When the value of the random access request field in the downlink control information in the first random access configuration period within a random access association period is 1, all random access opportunities within the random access association period to which the random access configuration period containing the downlink control information belongs are enabled; when the value of the random access request field in the downlink control information in the first random access configuration period within a random access association period is 0, all random access opportunities within the random access association period to which the random access configuration period containing the downlink control information belongs are disabled; when no downlink control information containing the random access request field is received, all random access opportunities within the random access association period to which the random access configuration period containing the downlink control information belongs are disabled by default.

[0281] Optionally, according to the random access request field in the downlink control information, enabling or disabling all random access opportunities within the random access association period in the first random access configuration refers to enabling all random access opportunities associated with the SSB within the random access association period.

[0282] Through the technical solution of this embodiment, specifically through the newly added random access request field in the downlink control information, all random access opportunities within the random access configuration period or the random access association period in the first random access configuration are dynamically enabled or disabled, so that the network device can perform preamble code detection only at the random access opportunity enabled by the downlink control information, thereby reducing network energy consumption; and / or, the network device can adaptively enable or disable all random access opportunities within the random access configuration period or the random access association period according to the number of terminal devices in the current service cell and / or the service frequency of the terminal device, and inform the terminal device through the downlink control information, thereby reducing the signaling interaction between the network device and the terminal device.

[0289] Optionally, when the service cell where the terminal device is located supports the cell DRX configuration, the terminal device can enable or disable all random access opportunities within the random access configuration period or random access association period in the first random access configuration according to the random access request field in the downlink control information during the activation time of the cell DRX and the inactivation time of the cell DRX.

[0290] Optionally, when the serving cell where the terminal device is located supports the cell DRX configuration, the terminal device may enable or disable all random access opportunities within the random access configuration period or the random access association period in the first random access configuration according to the random access request field in the downlink control information only during the inactive time of the cell DRX. During the active time of the cell DRX, the terminal device enables the random access opportunities within all random access configuration periods or random access association periods in the first random access configuration determined according to the radio resource control information.

[0291] Optionally, one random access opportunity may be associated with one or more SSBs.

[0292] Optionally, under the first trigger event, and in the first scenario and / or the second scenario, the terminal device sends msg1 and / or msgA at a random access opportunity in a random access configuration period enabled by the random access request field in the downlink control information.

[0293] Optionally, under the first trigger event and within the inactive time of cell DRX, the terminal device sends msg1 and / or msgA at a random access opportunity in a random access configuration period enabled by the random access request field in the downlink control information.

[0294] Referring to Figure 11, Figure 11 is a schematic diagram illustrating a first example according to the fifth embodiment. As shown in Figure 11, random access opportunities in a random access configuration period in a first random access configuration within the cell DRX inactive time are enabled or disabled based on the random access request field in the downlink control information. Dark squares indicate that the random access opportunities can be used for msg1 and / or msgA transmission. During the cell DRX inactive time, when the random access request field in the downlink control information is 1, all random access opportunities in the random access configuration period in which the downlink control information is located are enabled. During the cell DRX inactive time, when the random access request field in the downlink control information is 0, all random access opportunities in the random access configuration period in which the downlink control information is located are disabled. During the cell DRX inactive time, if no downlink control information containing the random access request field is received, all random access opportunities in the random access configuration period in which the downlink control information is located are disabled by default.

[0295] Optionally, under the first trigger event, and in the first scenario and / or the second scenario, the terminal device sends msg1 and / or msgA at a random access opportunity in a random access association period enabled by the random access request field in the downlink control information.

As shown in Figure 12, all random access opportunities within a random access association period within the cell DRX inactivity period are enabled or disabled based on the random access request field in the downlink control information. Optionally, the downlink control information is located in the first random access configuration period within the random access association period. Assume that a random access association period includes two random access configuration periods. During the inactive time of cell DRX, when the value of the random access request field in the downlink control information in the first random access configuration period within the random access association period is 1, all random access opportunities in the random access association period to which the random access configuration period where the downlink control information is located belongs are enabled; during the inactive time of cell DRX, when the value of the random access request field in the downlink control information in the first random access configuration period within the random access association period belongs is 0, all random access opportunities in the random access association period to which the random access configuration period where the downlink control information is located belongs are disabled; during the inactive time of cell DRX, when no downlink control information containing the random access request field is received, all random access opportunities in the random access association period to which the random access configuration period where the downlink control information is located belongs are disabled by default.

[0298] Optionally, during the inactive time of cell DRX, according to the random access request field in the downlink control information, enabling or disabling all random access opportunities within the random access association period in the first random access configuration refers to enabling all random access opportunities associated with SSB within the random access association period.

[0299] Through the technical solution of this embodiment, specifically through the newly added random access request field in the downlink control information, all random access opportunities within the random access configuration period or random access association period in the first scenario and / or the second scenario are enabled or disabled, thereby further increasing the sleep time of the network device in the first scenario and / or the second scenario, thereby reducing network energy consumption.

[0300] Sixth embodiment

[0301] Based on any of the above embodiments of the present application, this embodiment further discloses a method for determining a first random access configuration based on wireless resource control information, determining a second random access configuration based on the first random access configuration and a random access configuration index field in the downlink control information, and determining a random access timing based on the second random access configuration.

[0302] Optionally, determining the first random access configuration based on the radio resource control information includes: determining the random access configuration period and the preamble format, etc. based on a random access configuration index (prach-ConfigurationIndex) field in the radio resource control information.

[0303] Optionally, determining the second random access configuration according to the random access configuration index field in the downlink control information includes: determining the random access configuration period and the preamble format, etc. according to the random access configuration index field in the downlink control information.

[0304] Optionally, the preamble format determined by the second random access configuration is the same as the preamble format determined by the first random access configuration; the period of the random access opportunity determined by the second random access configuration is a preset multiple of the period of the random access opportunity determined by the first random access configuration; the number of synchronization signal blocks associated with the random access opportunity determined by the second random access configuration is the same as the number of synchronization signal blocks associated with the random access opportunity determined by the first random access configuration.

[0305] Optionally, the duration of the random access configuration period determined according to the random access configuration index field in the downlink control information is related to the number of terminal devices in the current serving cell and / or the service frequency of the terminal devices.

[0306] Referring to Figure 13, Figure 13 is a schematic diagram of a first example according to the sixth embodiment. As shown in Figure 13, a first random access configuration is determined based on radio resource control information, a second random access configuration is determined based on the first random access configuration and the random access configuration index field in the downlink control information, and a random access timing is determined based on the second random access configuration. For FR1 and FDD, Table 6.3.3.2-2 in protocol 38.211 is used to determine the random access configuration period. Assume that the subcarrier spacing of PUSCH is 15KHz. If the prach-ConfigurationIndex in the radio resource control information is 16, then according to the protocol, it can be known that the terminal device is in n SFN mod1=0 system frame (x=1, y=0. That is, n SFN The preamble of format 0 is transmitted on subframe 1 of the system frame with mod1=0,1,2,... Therefore, the random access configuration period determined based on the random access configuration index field in the above radio resource control information is 10ms. If the number of terminal devices in the current serving cell decreases and / or the service frequency of the terminal devices decreases, the network device can configure the prach-ConfigurationIndex field in the DCI sent to the terminal device to 9. If the prach-ConfigurationIndex field in the DCI is 9, it can be known from the protocol that the terminal device is in nSFN mod4=1 system frame (x=4, y=1. That is, n SFN The preamble of format 0 is transmitted on subframe 4 of the system frame (with mod4=1,5,9,...). Therefore, the random access configuration period is determined to be 40ms according to the random access configuration index field in the downlink control information. Then, the random access configuration period of the terminal device is changed from 10ms to 40ms. If the number of terminal devices in the current service cell is further reduced and / or the service frequency of the terminal device is further reduced, the network device can configure the prach-ConfigurationIndex field in the DCI sent to the terminal device to 4. If the prach-ConfigurationIndex field in the DCI takes the value of 4, it can be known from the protocol that the terminal device is in n SFN mod8=1 system frame (x=8,y=1. That is, n SFN The preamble of format 0 is transmitted on subframe 1 of the system frame (system frame with mod8=1,9,...). Therefore, the random access configuration period is determined to be 80ms based on the random access configuration index field in the downlink control information. Furthermore, the random access configuration period of the terminal device is changed from 40ms to 80ms. Therefore, according to the number of terminal devices in the current serving cell and / or the service frequency of the terminal device, Figure 13 shows that the random access configuration period of the terminal device changes from 10ms-->40ms-->80ms.

[0307] Through the technical solution of this embodiment, the current random access configuration period is adjusted in real time by using the newly added random access configuration index field in the downlink control information, so that the duration of the random access configuration period is more in line with the number of terminal devices in the service cell and / or the service frequency requirements of the terminal devices, and the flexibility of configuring the random access configuration period is improved.

[0308] Seventh embodiment

[0309] Based on any of the above embodiments of the present application, this embodiment further discloses a method for determining a first random access configuration based on wireless resource control information, determining a second random access configuration in a first scenario and / or a second scenario according to the first random access configuration and a random access configuration index field in the downlink control information, and determining a random access timing according to the second random access configuration.

[0310] Optionally, the first scenario is within an inactive time of discontinuous reception of the cell.

[0311] Optionally, the second scenario is within an activation time of discontinuous reception of the cell.

[0312] Optionally, determining the first random access configuration based on the radio resource control information includes: determining the random access configuration period and the preamble format, etc. based on a random access configuration index (prach-ConfigurationIndex) field in the radio resource control information.

[0313] Optionally, determining the second random access configuration in the first scenario and / or the second scenario according to the random access configuration index field in the downlink control information includes: during the activation time of cell DRX and / or the inactivation time of cell DRX, determining the random access configuration period and preamble code format, etc. according to the random access configuration index field in the downlink control information.

[0314] Optionally, under the first trigger event, during the inactive time of cell DRX, the terminal device sends msg1 and / or msgA at the random access timing of the second random access configuration determined by the random access configuration index field in the downlink control information.

[0315] Optionally, the preamble format determined by the second random access configuration is the same as the preamble format determined by the first random access configuration; the period of the random access opportunity determined by the second random access configuration is a preset multiple of the period of the random access opportunity determined by the first random access configuration; the number of synchronization signal blocks associated with the random access opportunity determined by the second random access configuration is the same as the number of synchronization signal blocks associated with the random access opportunity determined by the first random access configuration.

[0316] Optionally, the duration of the random access configuration period determined according to the random access configuration index field in the downlink control information is related to the number of terminal devices in the current serving cell and / or the service frequency of the terminal devices.

[0317] Optionally, when the service cell where the terminal device is located supports the cell DRX configuration, the terminal device can determine the second random access configuration according to the random access configuration index field in the downlink control information during the activation time of the cell DRX and / or the inactivation time of the cell DRX, and determine the random access timing according to the second random access configuration.

[0318] Optionally, when the serving cell where the terminal device is located supports the cell DRX configuration, the terminal device may determine the second random access configuration based on the random access configuration index field in the downlink control information only during the inactive time of the cell DRX, and determine the random access timing based on the second random access configuration. During the active time of the cell DRX, the terminal device determines the first random access configuration based on the random access configuration index field in the radio resource control information, and determines the random access timing based on the first random access configuration.

[0319] Referring to FIG. 14 , FIG. 14 is a schematic diagram illustrating a first example according to the seventh embodiment. As shown in FIG. 14 , during the cell DRX inactive time, a second random access configuration is determined based on the random access configuration index field in the downlink control information, and a random access timing is determined based on the second random access configuration. Furthermore, during the cell DRX active time, a first random access configuration is determined based on the random access configuration index field in the radio resource control information configuration, and a random access timing is determined based on the first random access configuration.

[0320] Through the technical solution of this embodiment, specifically by adjusting the random access configuration period in the first scenario and / or the second scenario in real time through the newly added random access configuration index field in the downlink control information, the sleep duration of network devices can be further increased, thereby reducing network energy consumption. Furthermore, by flexibly adjusting the random access configuration period through downlink control information, the random access configuration period can be better adapted to the number of terminal devices in the current serving cell and / or the service frequency of the terminal devices, thereby reducing the random access latency of the terminal devices.
