Detailed Description
Features and exemplary embodiments of various aspects of the present application are described in detail below to make the objects, technical solutions and advantages of the present application more apparent, and to further describe the present application in conjunction with the accompanying drawings and the detailed embodiments. It should be understood that the specific embodiments described herein are merely configured to explain the present application and are not configured to limit the present application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other like elements in a process, method, article or apparatus that comprises the element.
The power consumption of the ue is an important issue of mobile communication interest, and various schemes for improving the power consumption of the ue, such as discontinuous reception (Connected Discontinuous Reception, CDRX), bandwidth Part (BWP), intelligent pre-scheduling in uplink, dynamic adaptive in uplink, and the like, specifically include the following steps:
connected state discontinuous reception CDRX: after the user equipment enters a radio resource CONTROL (RRC, RADIORESOURCE CONTROL) connection state, the 4G base station eNB and the 5G base station gNB respectively configure CDRX parameters, and the user equipment wakes up periodically to receive downlink data, so that the power consumption of the user equipment is saved.
BWP (Bandwidth Part): the working principle is as shown in fig. 4, and the larger the working bandwidth of the user equipment UE is, the higher the power consumption is. Compared with 4G, the 5G bandwidth is increased from 20MHz to 100MHz, the sampling rate of the front-end analog signal is increased, and the signal processing complexity of the algorithm module is increased. BWP allows the UE to operate on a portion of the total bandwidth. When the UE transmits low-rate service, the UE works in a narrow bandwidth; when the UE transmits high rate traffic, it operates at a large bandwidth.
Uplink intelligent pre-scheduling: as shown in fig. 5, compared with the periodic pre-scheduling triggered after the common uplink pre-scheduling UE sends the scheduling request (Scheduling Request, SR), the intelligent pre-scheduling is based on the triggering of the pre-scheduling when the downlink data packet arrives, so that the problem that the user equipment cannot enter the CDRX sleep period after the common uplink pre-scheduling is started can be effectively solved, the data uploading delay is ensured to be short, and meanwhile, the power consumption is moderate.
Uplink waveform dynamic adaptation: the peak-to-average ratio PAPR of the LTE uplink and the new air interface NR physical layer uplink DFT-S-OFDM is smaller than that of the NR physical layer uplink and downlink CP-OFDM, so that the DFT-S-OFDM is adopted, the linearity reserved space of the user equipment radio frequency power amplifier PA is larger, the PA working efficiency is higher, and the lower power consumption can be used to achieve the same transmitting power as the CP-OFDM; on the contrary, under the same power consumption, the DFT-S-OFDM transmission power is higher (the PA transmission power is 1dB higher), and the uplink coverage area can be effectively improved. The current base station mainly adopts CP-OFDM, and compared with DFT-S-OFMD, the CP-OFDM can adjust uplink 2 streams, supports discontinuous scheduling and has higher frequency spectrum utilization rate. But it is suggested that the base station can support uplink waveform dynamic adjustment to DFT-S-OFDM through radio resource CONTROL (RRC, RADIORESOURCE CONTROL) signaling reconfiguration.
The above-mentioned several existing power consumption promotion schemes are more power consumption optimization performed for the user equipment already under LTE (LONG TERM EVOLUTION ) -NR dual connectivity. Whether C-DRX, BWP, uplink intelligent language scheduling and uplink waveform self-adaption are carried out, the power consumption optimization is carried out on the NR auxiliary carrier side by considering that the user equipment is in a double-connection state. In addition, in the use of actual user equipment, more scenes exist, and the speed of the 4G network can meet the use requirements of users, such as WeChat, web browsing, mobile payment, vehicle drop and the like.
In a NON-independent networking mode (NSA), the user equipment is required to keep dual connection of LONG TERM EVOLUTION (LTE) -NR, and a chip Transceiver and a radio frequency PA of the user equipment are always in working states, and especially the NR frequency band of the other path is 100MHz bandwidth, which improves the power consumption of the user equipment by approximately 5 times compared with the 4g 20 MHz. Meanwhile, in existing applications, the rate of many services (e.g., weChat chat, web browsing, news reading) is not always required to be high.
Fig. 6 is a schematic diagram of an overall architecture of a non-independent networking in a fifth generation mobile communication system, as shown in fig. 6, a core network of the non-independent networking architecture is EPC (Evolved Packet Core), a user equipment is anchored in a 4G frequency band, and can access the core network through LONG TERM EVOLUTION (LTE) of a 4G radio air interface, and for carrying data, service plane data transmission can be performed by establishing a dual connection with a NR SECONDARY CELL GROUP (SCG).
The single carrier of the 4G wireless air interface is 20MHz, the auxiliary carrier of the 5G wireless air interface is 100MHz, and the rate of the user equipment is greatly improved after the new air interface NR auxiliary carrier is added (the downlink theoretical rate of the 4G network is 100Mbps, the downlink theoretical rate of the 5G network is 1.7Gbps, but the power consumption of the user equipment is obviously improved while the rate is improved.
In order to solve the problems in the prior art, embodiments of the present application provide a method, an apparatus, a device, and a storage medium for reducing power consumption of a user equipment. According to the embodiment of the application, whether the SCG of the secondary cell group needs to be added or removed can be intelligently judged based on the condition that the secondary cell group is added by the user equipment cell and the transmission rate of the current transmission service of the user equipment, and the SCG is not added or removed when the low-rate service of the user equipment is transmitted, so that the current power consumption of the 5G user equipment can be reduced. The method for reducing the power consumption of the user equipment provided by the embodiment of the application is first described below.
Fig. 7 is a flowchart illustrating a method for reducing power consumption of a user equipment according to an embodiment of the present application. As shown in fig. 7, the method may include the steps of:
s70, when entering the LTE connection state from the LTE idle state, determining whether a cell to which the user equipment belongs adds the secondary cell group SCG, and determining the transmission rate of the current transmission service of the user equipment.
When entering the LTE connected state from the long term evolution LTE idle state, the 5G user equipment may be in one of two states: a dual connection with added SCG status, i.e., in LONG TERM EVOLUTION (LTE) -NR; and, no SCG state is added, i.e., dual connectivity is not in LONG TERM EVOLUTION (LTE) -NR.
S72, when the cell to which the user equipment belongs does not add SCG, and when the transmission rate is lower than the preset rate, a first measurement report is not reported to the network equipment to which the user equipment belongs, wherein the first measurement report characterizes that the service quality of the SCG is larger than a preset threshold.
In the prior art, when the service quality of the SCG is greater than a preset threshold (which may be typically set to-115 dBm), the ue reports a first measurement report, and the 4G anchor cell device performs an operation of adding the NR cell SCG (SECONDARY CELL GROUP). Fig. 8 is a signaling interaction diagram of a ue and a network device to which the ue belongs in an embodiment of the present application, as shown in fig. 8, in the embodiment of the present application, when a transmission rate is lower than a preset rate, a first measurement report is not reported to the network device to which the ue belongs, and the network device cannot add an NR SCG to the ue, so as to achieve the goal of reducing power consumption of the ue.
And S74, when the SCG is added to the user equipment, and when the transmission rate is lower than the preset rate, sending the SCG dismantling information to the network equipment.
As shown in fig. 8, when the SCG is added to the user equipment and when the transmission rate is lower than the preset rate, it is indicated that the user equipment does not need to employ dual connection, and at this time, the removal SCG information is transmitted to the network equipment.
In one embodiment, the teardown SCG information may include at least one of:
t310 timer timeout information, SCG synchronization failure information, secondary cell group media intervention control layer (Secondary Cell Group Media Access Control, SCG MAC) random access problem information, secondary cell group radio link control layer (Secondary Cell Group Radio Link Control, SCG RLC) has reached maximum number of retransmissions information, signaling radio bearer (Signalling Radio Bearers, SRB) 3 integrity check failure information, neighbor cell radio resource control RRC reconfiguration message reconfiguration failure message.
In the prior art, after receiving the SCG Failure information, the network device performs an SCG removal operation. The 3GPP specifies SCG Failure mainly for several reasons:
the T310 timer times out and the UE will report SCG Failure Information NR, the reason being defined as T310-timeout;
the SCG synchronization fails, the user equipment requests reconfiguration, and the UE reports SCG Failure Information NR for defining as synchReconfigFaure-SCG;
SCG MAC random access is problematic, UE will report SCG FailureInformationNR for reasons defined as randommacess problem;
the SCG RLC reaches the maximum retransmission times, and the UE reports SCG FailureInformationNR for the reason defined as the rl-MaxNumRetx;
SRB3 integrity check fails and the UE will report SCG FailureInformationNR for reasons defined as SRB-IntermityFaure;
failure to reconfigure an NR Radio Resource CONTROL (RRC) reconfiguration message may be reported SCG FailureInformationNR for a reason defined as scg-reconfigFailure.
Therefore, the embodiment of the present application sets the removal SCG information as SCG Failure information. After receiving the SCG Failure, the network performs link removal of the NR cell SCG (SECONDARY CELL GROUP), thereby achieving the goal of reducing the power consumption of the user equipment.
In one embodiment, when the tear down SCG information includes T310 timer timeout information, the tear down SCG information further includes:
and the fault frequency measurement result list is characterized in that the recorded content of the preset position of the list is preset content.
Since most operators use SCG Failure (cause value T310 is overtime) as an index for measuring NR wireless quality of the current network, frequent reporting of SCG Failure (T310 is overtime) by the user equipment can seriously affect statistics of NR wireless link indexes of the current network due to power consumption saving requirements. In view of the drawbacks, the embodiment of the application reports the failure frequency measurement result list while the user equipment reports the demolition SCG information (cause value T310 is overtime), and simultaneously reports the physical cell identity (Peripheral Component Interconnect, PCI) and the absolute radio channel number (Absolute Radio Frequency Channel Number-ARFCN). Unlike normal reporting of the PCI, ARFCN for the current cell, the NR cell SCG (SECONDARY CELL GROUP) is actively released by the user equipment having a low traffic rate, with the user equipment PCI and ARFCN reporting as 0. With reference to the 3GPP standard procedure, ARFCN-ValueNR-r15=0 and pci-r15=0 are reported in MeasResultFreqListFailNR-r15, SEQUENCE=1. The programming is as follows:
based on the fault frequency measurement result list, when the statistics of the NR wireless link indexes of the existing network fails, carrying out secondary association of cell information in the fault frequency measurement result list, and eliminating ARFCN-ValueNR-r15=0 and pci-r15=0 in the statistics of the wireless link failures in the fault frequency measurement result list so as to ensure the reality and accuracy of the statistics.
In one embodiment, S74 may include:
the application platform (Application Platform, AP) layer of the user equipment triggers the base station platform (Baseband Platform, BP) layer of the user equipment to send tear down SCG information.
In one embodiment, before detecting the transmission rate of the current transmission service of the user equipment, the method further comprises:
detecting whether a time period of a window for detecting the transmission rate preset by an application platform AP layer of user equipment is overtime or not; under the condition that the time is not overtime, detecting the transmission rate of the current transmission service of the user equipment; in case of a timeout, the time period of the window is reset, thereby ensuring the accuracy of the measured transmission rate.
According to the method for reducing the power consumption of the user equipment, whether the SCG of the secondary cell group needs to be added or removed can be intelligently judged based on the condition that the secondary cell group is added by the user equipment cell and the transmission rate of the current transmission service of the user equipment, and the SCG is not added or removed when the low-rate service of the user equipment is transmitted, so that the current power consumption of the 5G user equipment can be reduced.
Fig. 7-8 illustrate a method for reducing power consumption of a user equipment, and the apparatus provided in the embodiments of the present application are described below with reference to fig. 9 and fig. 10.

a determining module 90, configured to determine whether the cell to which the user equipment belongs adds the secondary cell group SCG when entering the LTE connection state from the long term evolution LTE idle state, and determine a transmission rate of the current transmission service of the user equipment.

And a sending module 92, configured to, when the cell to which the ue belongs does not add SCG, and when the transmission rate is lower than the preset rate, not report a first measurement report to the network device to which the ue belongs, where the first measurement report characterizes that the service quality of the SCG is greater than the preset threshold.
In the prior art, when the service quality of the SCG is greater than a preset threshold (which may be typically set to-115 dBm), the ue reports a first measurement report, and the 4G anchor cell device performs an operation of adding the NR cell SCG (SECONDARY CELL GROUP). Fig. 8 is a signaling interaction diagram of a ue and a network device to which the ue belongs in an embodiment of the present application, as shown in fig. 8, in the embodiment of the present application, when a transmission rate is lower than a preset rate, a first measurement report is not reported to the network device to which the ue belongs, and the network device cannot add an NR SCG to the ue, so as to achieve the goal of reducing power consumption of the ue.
A sending module 92, configured to send the removal SCG information to the network device when the SCG is added to the user device and the transmission rate is lower than the preset rate.
As shown in fig. 8, when the SCG is added to the user equipment and when the transmission rate is lower than the preset rate, it is indicated that the user equipment does not need to employ dual connection, and at this time, the removal SCG information is transmitted to the network equipment.
In one embodiment, the teardown SCG information may include at least one of:

In the prior art, after receiving the SCG Failure information, the network device performs an SCG removal operation. The 3GPP specifies SCG Failure mainly for several reasons:
the T310 timer times out and the UE will report SCG Failure Information NR, the reason being defined as T310-timeout;
the SCG synchronization fails, the user equipment requests reconfiguration, and the UE reports SCG Failure Information NR for defining as synchReconfigFaure-SCG;

SRB3 integrity check fails and the UE will report SCG FailureInformationNR for reasons defined as SRB-IntermityFaure;
failure to reconfigure an NR Radio Resource CONTROL (RRC) reconfiguration message may be reported SCG FailureInformationNR for a reason defined as scg-reconfigFailure.
Therefore, the embodiment of the present application sets the removal SCG information as SCG Failure information. After receiving the SCG Failure, the network performs link removal of the NR cell SCG (SECONDARY CELL GROUP), thereby achieving the goal of reducing the power consumption of the user equipment.
In one embodiment, when the tear down SCG information includes T310 timer timeout information, the tear down SCG information further includes:
and the fault frequency measurement result list is characterized in that the recorded content of the preset position of the list is preset content.
Since most operators use SCG Failure (cause value T310 is overtime) as an index for measuring NR wireless quality of the current network, frequent reporting of SCG Failure (T310 is overtime) by the user equipment can seriously affect statistics of NR wireless link indexes of the current network due to power consumption saving requirements. In view of the drawbacks, the embodiment of the application reports the failure frequency measurement result list while the user equipment reports the demolition SCG information (cause value T310 is overtime), and simultaneously reports the physical cell identity (Peripheral Component Interconnect, PCI) and the absolute radio channel number (Absolute Radio Frequency Channel Number-ARFCN). Unlike normal reporting of the PCI, ARFCN for the current cell, the NR cell SCG (SECONDARY CELL GROUP) is actively released by the user equipment having a low traffic rate, with the user equipment PCI and ARFCN reporting as 0. With reference to the 3GPP standard procedure, ARFCN-ValueNR-r15=0 and pci-r15=0 are reported in MeasResultFreqListFailNR-r15, SEQUENCE=1. The programming is as follows:
/>
based on the fault frequency measurement result list, when the statistics of the NR wireless link indexes of the existing network fails, carrying out secondary association of cell information in the fault frequency measurement result list, and eliminating ARFCN-ValueNR-r15=0 and pci-r15=0 in the statistics of the wireless link failures in the fault frequency measurement result list so as to ensure the reality and accuracy of the statistics.
In one embodiment, the sending module 92 may be specifically configured to:
the application platform (Application Platform, AP) layer of the user equipment triggers the base station platform (Baseband Platform, BP) layer of the user equipment to send tear down SCG information.
In one embodiment, the apparatus further includes a detecting module 94, configured to detect whether a time period of a window preset by an AP layer of the user equipment for detecting a transmission rate is timeout before detecting a transmission rate of a current transmission service of the user equipment; under the condition that the time is not overtime, detecting the transmission rate of the current transmission service of the user equipment; in case of a timeout, the time period of the window is reset, thereby ensuring the accuracy of the measured transmission rate.
According to the device for reducing the power consumption of the user equipment, whether the SCG of the secondary cell group needs to be added or removed can be intelligently judged based on the condition that the secondary cell group is added by the user equipment cell and the transmission rate of the current transmission service of the user equipment, and the SCG is not added or removed when the low-rate service of the user equipment is transmitted, so that the current power consumption of the 5G user equipment can be reduced.
