Description

Technical Field

[0002] Discontinuous reception (DRX) is a wireless communication system that uses the intermittent arrival of data packets to allow user terminal devices to enter sleep mode at specific times when there is no data transmission, without detecting the physical control channel (PDCCH) signal, thereby reducing the power consumption of the user terminal and achieving the function of saving power and extending the standby time of the user terminal.

[0003] The processing flow of DRX is mainly that the base station calculates the time when the user terminal device is in the activated state and the time when it enters the dormant state according to the DRX configuration sent to the user terminal device, and sends data according to the calculated activation state time. If the user terminal device needs to actively send data, it will notify the base station through a scheduling request (SR, Scheduling Request), and the base station will directly schedule according to the scheduling request. However, due to various types of noise and interference in the wireless channel, the uplink and downlink scheduling of the base station and the user terminal will fail, which will lead to the failure of the wireless link, resynchronization or re-establishment, etc., making the wireless communication system unstable when using DRX.

[0043] In the process of wireless communication between a base station and a user terminal device, a discontinuous reception (DRX) energy-saving mechanism is generally used to reduce the power consumption of the user terminal device. The user terminal device includes a mobile phone, an Internet of Things device, etc. Figure 1 A schematic diagram of the processing flow of discontinuous reception is provided, refer to Figure 1 , Figure 1 There are two terminals that perform wireless communication with the base station, but in actual applications, there can be multiple user terminals. When the base station calculates the time when the user terminal device is in the activated state and the time when it enters the dormant state according to the DRX configuration sent to the user terminal device, and sends data according to the calculated activation state time. When the user terminal device sends a scheduling request (SR, Scheduling Request) to the base station, the base station needs to respond in time to ensure that the uplink and downlink between the base station and the user terminal device are normal, otherwise the user terminal device will re-initiate access and re-establish the uplink and downlink. When the base station determines that the terminal performing wireless communication is in the activation period or receives a scheduling request sent by the terminal, it sends data; when the user terminal sends a scheduling request, and the base station determines that the user terminal is in the activation period and has uplink data to send, the base station directly schedules according to the scheduling request.

[0044] However, due to the existence of various noises and interferences in the wireless channel, the base station inevitably mistakenly detects noises and interferences as SRs sent by the user terminal at the SR resource time point, causing the base station to miscalculate and extend the activation time of the user terminal in accordance with the protocol. The base station sends data when the user terminal device is not activated and cannot receive the correct message feedback, causing uplink and downlink scheduling failures, and then causing wireless link failures, resynchronization and re-establishment, resulting in a waste of air interface resources. Furthermore, in a mobile communication system, the base station sending data to the user terminal device is called downlink, and the user terminal device sending data to the base station is called uplink. The present application provides a wireless communication method, which uses different strategies according to the configuration of the DRX activation time to improve the stability of the wireless communication system while ensuring latency and functional integrity, and effectively reduce various air interface signaling problems caused by DRX.

[0045] In this embodiment, a wireless communication method is provided. Figure 2 is a flowchart of a wireless communication method provided in an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0046] Step S210, receiving a scheduling request sent by a user equipment, and acquiring a discontinuous reception parameter of the user equipment; the user equipment is connected to a base station for communication; and the discontinuous reception parameter includes a first time period.

[0047] Among them, when the user terminal equipment needs to actively send data to the base station during the wireless communication process with the base station, the user equipment initiates a scheduling request to the base station. After the base station receives the scheduling request sent by the user equipment, it obtains the discontinuous reception parameters set in advance for the user equipment. When the user equipment receives the discontinuous reception parameter configuration, it performs DRX operation according to these discontinuous reception parameters. Furthermore, the discontinuous reception parameters also include a first time period, which is a time period in which the user equipment can communicate with the base station. During the first time period, the base station and the user equipment perform uplink and downlink scheduling.

[0048] Specifically, when a user equipment accesses the network of a base station for the first time, it will establish a connection with the base station through a random access process. During this process, the user equipment will receive a system information broadcast (System Information Block, SIB), which contains the basic parameters of discontinuous reception of the network. The base station configures discontinuous reception parameters for the user equipment through RRC (Radio Resource Control) signaling. These parameters may include: the period for the user equipment to switch between continuous reception and sleep states - DRX cycle, the time for the user equipment to stay awake and monitor the downlink in each DRX cycle - On DurationTime, the waiting time before the user equipment enters DRX mode after not receiving data or control information - DRX InactivityTimer, and responding to the network's shorter DRX cycle - Short DRX Cycle.

[0049] Step S220, in response to the scheduling request, sending a control instruction to the user equipment; determining a first time when the user equipment receives the control instruction, and a second time when the user equipment sends communication data according to the control instruction; determining a second time period according to the first time and the second time.

[0050] When the base station receives the scheduling request sent by the user equipment, it responds to the scheduling request, feeds back the control instruction to the user equipment, and determines the first time when the user equipment receives the control instruction. When the user equipment receives the control instruction, it sends communication data to the base station according to the control instruction, and determines the second time when the communication information is sent.

[0051] After the first moment and the second moment are acquired, the time interval between the first moment and the second moment is determined as the second time period. The second time period specifically includes the time interval from when the user equipment receives the control instruction to when the user terminal sends actual communication data according to the control instruction.

[0052] Step S230: performing scheduling feedback to the user equipment according to the first time period and the second time period.

[0053] Among them, the base station determines whether the user equipment is in an activated state according to the first time period and the second time period obtained, and determines the DRX activation time and activation time interval of the user equipment to obtain a judgment result, and then performs different scheduling feedback according to the judgment result to optimize the existing DRX function, and then improves the stability and delay of wireless transmission on the basis of realizing the basic DRX function according to different scheduling conditions of the user equipment. Exemplarily, the user equipment here is the aforementioned user terminal equipment and terminal.

[0054] Through the above steps, after receiving the scheduling request of the user equipment, the base station determines the first time period in the discontinuous reception parameters pre-configured for the user equipment; at the same time, responds to the scheduling request sent by the user equipment, sends a control instruction to the user equipment, and obtains the time interval for the user equipment to receive the control instruction and send communication data according to the control instruction, and then determines different scheduling situations according to the first time period and the second time period of the time interval, and then executes different scheduling feedback, which is beneficial to improve the system stability of using DRX in wireless communication.

[0055] In some of the embodiments, step S230 performs scheduling feedback on the user equipment according to the first time period and the second time period, including steps S231 to S232.

[0056] Step S231: when the first time period is less than or equal to the second time period, in response to the scheduling request, scheduling feedback is performed on the user equipment within the first time period.

[0057] Among them, when it is judged that the first time period is less than or equal to the second time period, that is, the DRX activation time of the user equipment is less than or equal to the maximum time for the user equipment to receive the uplink DCI (Downlink Control Information) to PUSCH (Physical Uplink Shared Channel), the base station calculates the activation time point of the user equipment and determines the activation period of the user equipment, and then feedbacks the scheduling request initiated by the user equipment during the activation period. Regardless of whether the scheduling request is initiated by the user equipment, the base station can perform scheduling feedback.

[0058] Step S232, the discontinuous reception parameters also include an interval period of the first time period; determine whether the interval period of the first time period is less than a preset scheduling request duration, and if so, respond to the scheduling request and perform scheduling feedback to the user equipment within the first time period.

[0059] The discontinuous reception parameter also includes an interval period of the first time period, that is, an activation time interval of the DRX of the user equipment. At the same time, a scheduling request time of the user equipment is preset, specifically, a maximum number of retransmission times of the scheduling request. When the interval period of the first time period is less than the configured maximum number of retransmission times of the scheduling request, the base station responds to the scheduling request of the user equipment and performs scheduling feedback to the user equipment during the activation period of the user equipment, that is, the first time period.

[0060] Through the above steps, if the base station side receives an SR sent by a user terminal device, it does not immediately provide feedback to the user terminal device. By calculating the activation time point of the user terminal device, the activation period of the user terminal device is determined, data scheduling is performed during the activation period, and the received SR is fed back. Feedback is performed during the activation period. Regardless of whether the SR is an error detection, correct SR feedback scheduling can be performed, which is beneficial to improving the efficiency of responding to user scheduling requests. At the same time, while ensuring the complete realization of the DRX function, the stability of the wireless communication system is improved.

[0061] In some of the embodiments, it is determined whether the user equipment is in the interval period of the first period based on the initial communication time, and if so, the communication time is updated; and it is determined whether the user equipment is in the first period based on the updated communication time.

[0062] Among them, after receiving the scheduling request sent by the user equipment, the base station determines whether the user equipment is in the first time period, i.e., the activation period, according to the time when the scheduling request is received. If so, scheduling feedback is performed according to the scheduling request sent by the user equipment; if the user equipment is in the interval period of the first time period, the communication time is updated in real time, and then it is determined whether the user equipment is in the first time period, i.e., the activation period, according to the updated communication time. Specifically, the communication time is calculated according to the 3GPP protocol.

[0063] Through the above steps, it is determined whether the user equipment is in the first time period according to the real-time communication time, and scheduling feedback is implemented according to the determination result, which is beneficial to improving the system stability after using DRX.

[0064] In some of the embodiments, in step S230, scheduling feedback is performed on the user equipment according to the first time period and the second time period, including: when the first time period is greater than the second time period, scheduling feedback is performed on the user equipment in response to the scheduling request; after receiving the scheduling feedback result sent by the user equipment, determining whether the scheduling request is initiated by the user equipment according to the scheduling feedback result.

[0065] Among them, when the first time period is greater than the second time period, that is, the DRX activation time of the user equipment is greater than the maximum time for the user equipment to receive the uplink DCI to send to PUSCH, the scheduling feedback result received from the user equipment is used to determine whether the scheduling request is sent by the user equipment or a scheduling request obtained by the base station due to interference detection error.

[0066] Further, determining whether the scheduling request is initiated by the user equipment based on the scheduling feedback result includes: when it is determined that the scheduling request is not initiated by the user equipment, determining whether the feedback signal strength in the scheduling feedback result exceeds a preset signal strength threshold; when the feedback signal strength exceeds the preset signal strength threshold, extending the first time period.

[0067] When the scheduling request detection of the base station is wrong, the event of scheduling feedback is recorded, and it is determined whether the feedback signal strength exceeds the preset signal strength threshold. If the scheduling request detection result shows that the scheduling is wrong, but the signal strength is good, then the first time period of the user equipment is extended, that is, the activation period of the user equipment is updated and extended.

[0068] Through the above scheme, the sender of the scheduling request is detected according to the scheduling feedback result, thereby ensuring the functional integrity and delay of DRX, which is beneficial to improving the stability of the system after DRX is turned on.

[0069] In some of the embodiments, the wireless communication method further includes: when the first time period is greater than the second time period, and the interval period of the first time period is greater than a preset scheduling request duration, sending an instruction to restart the timer to the user equipment to achieve communication information synchronization.

[0070] Among them, when the DRX activation time of the user equipment is greater than the maximum time for the user equipment to receive the uplink DCI (Downlink Control Information) to send to PUSCH (Physical Uplink Shared Channel), and the DRX activation time interval is greater than the configured SR maximum retransmission time, since the activation time interval, i.e., the interval of the first time period, is large, it is easier to cause the user terminal equipment to not interact with the base station during sleep, thereby causing the information between the base station and the user equipment to be out of sync. Therefore, when the activation time of the user equipment is reached, the base station needs to send a command to restart the timer to the user equipment, notifying the user equipment to restart the DRX timer. At this time, the base station and the user equipment align the timer and synchronize the communication information including time and frequency, further improving the system stability after DRX is turned on.

[0071] The present embodiment is described and illustrated by means of specific examples below.

[0072] The present application provides a DRX optimization method. Figure 3 is a flowchart of a wireless communication method provided in this specific embodiment, refer to Figure 3When the base station receives the SR initiated by the user equipment, it obtains the pre-configured DRX parameter configuration of the user equipment, that is, the discontinuous reception parameter in the above-mentioned embodiment; then, according to the DRX parameter configuration, it determines whether to immediately schedule and update the activation period according to the scheduling request of the user equipment, or to determine the activation period after the user equipment feeds back the scheduling result. When it is necessary to determine the activation period according to the scheduling feedback result fed back by the user equipment, the uplink and downlink of the base station and the user equipment are synchronized to achieve the stability of the use of the DRX process during the wireless communication process between the base station and the user equipment.

[0073] Specifically, in one embodiment, when the DRX activation time of the user terminal device is less than or equal to the maximum time from the user terminal receiving the uplink DCI to the PUSCH sending, or the DRX activation time interval is less than the configured SR maximum retransmission time, the following scheme is adopted:

[0074] Figure 4 is a flowchart of the scheduling method provided in this specific embodiment. Figure 5 If the base station receives a scheduling request sent by a user equipment, it does not immediately provide feedback to the user equipment; instead, it calculates the activation time point of the user terminal equipment to determine the activation period of the user terminal equipment, that is, the first time period in the aforementioned embodiment, and performs data scheduling during the activation period, that is, feedback is given to the received SR, and feedback is given during the activation period. Regardless of whether the SR is an error detection, correct SR feedback scheduling can be performed. When the user equipment is not in the activation period, the activation time is updated until the user equipment is in the activation period, and feedback is given to the scheduling request of the user equipment during the activation period. Here, the activation period of the user equipment is the first time period in the aforementioned embodiment; the activation time point here is the communication time in the aforementioned embodiment. This solution can ensure the complete implementation of the DRX function while improving the stability of the system after DRX is turned on, but it will cause a slight increase in latency.

[0075] Specifically, calculating the activation time point of the user equipment may include two calculation methods: 1. Involving a timer, if a short format DRX is used, the specific calculation formula is:

[0076] [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle)

[0077] If the long format DRX is used, the specific calculation formula is:

[0078] [(SFN×10)+subframe number]modulo(drx-LongCycle)=drx-StartOffset

[0079] Among them, SFN is the frame number of the air interface of the communication system, subframe number is the subframe number, drx-ShortCycle is the short cycle, drx-LongCycle is the long cycle, and drx-StartOffset is the activation time point. Among them, the base station sends the corresponding user equipment through the RRC (Radio Resource Control) message to ensure the consistency between the base station and the user equipment.

[0080] In another embodiment, when the DRX activation time of the user terminal device is greater than the maximum time from the terminal receiving the uplink DCI to the PUSCH sending, and the DRX activation time interval is less than the configured SR maximum retransmission time, the following scheme is adopted: Figure 5 is a flow chart of another scheduling method provided by this specific embodiment. Figure 5 As shown in the figure, if the base station receives an SR sent by a user terminal device, it will immediately perform feedback scheduling for the user terminal device and record the feedback scheduling time. During this period, the SR is considered to be an error detection and the activation time is not extended. Afterwards, it is determined whether the SR scheduling result is received. If the feedback scheduling result is not received or the feedback scheduling result time is exceeded, the scheduling is terminated.

[0081] If the feedback scheduling result is received or the feedback scheduling result time is exceeded, the SR scheduling result is judged whether it is wrong through the received result and the feedback signal strength, that is, whether the SR is sent by the real user equipment or the base station is wrongly detected. If it is an error detection but the scheduling signal strength is good, the original process is retained, the feedback scheduling time is clearly recorded, and the activation time is updated and extended. If the SR is truly sent by the user terminal equipment, the activation time and time point of the user terminal equipment are recalculated according to the recorded feedback scheduling time; this solution can ensure the integrity of the DRX function and the unchanged delay, and improve the stability of the system after DRX is turned on.

[0082] In another embodiment, when the DRX activation time of the user terminal device is greater than the maximum time from the terminal receiving the uplink DCI to the PUSCH sending, and the DRX activation time interval is greater than the configured SR maximum retransmission time, the following scheme is adopted: Figure 6Based on the method, if the DRX activation time interval is large, it is easy to cause the user terminal device to not interact with the base station during sleep, and no data is sent for a long time, which will cause the time, frequency and other information between the base station and the user terminal device to be out of sync. Therefore, when the DRX activation time interval is large, each time the user terminal device activation time is reached, the MAC control element (MACCE) of DRX specified in the communication protocol is sent to notify the terminal to restart the DRX timer, the base station and the user equipment align the timer, and synchronize the time, frequency and other information at the same time; this solution can ensure the integrity of the DRX function and improve the stability of the system after DRX is turned on.

[0083] Through the above solution, when DRX is turned on, the system stability can be improved on the basis of realizing the DRX function, various wireless link problems caused by wireless channel fluctuations can be prevented, and the stability of the wireless communication system can be improved.
