Detailed Description
As described above, with the development of current communication technology and the increasing demand for communication, in a 5G communication system, not only high speed but also low power consumption is required. For example,
the power consumption requirements of the china mobile to 4G terminals, including terminals with downlink Aggregation (CA) capability, are shown in table 1, where table 1 is as follows:
TABLE 1
It should be noted that the power consumption requirement shown in table 1 is the power consumption requirement for the most frequently used telephone service of the user, and the requirement is provided under the condition of fully evaluating the user experience and the standby capability, while for 5G, even if the allocated system bandwidth is 60M, 100M or more, if only the telephone service is carried out, no more power consumption should be consumed, otherwise, the 5G technology has no advantage for the user in terms of voice.
In addition, for data services, such as File Transfer Protocol (FTP) services executed by a terminal, the requirements of power consumption and actual measurement results of some terminals by china mobile can be shown in table 2, where table 2 is as follows:
TABLE 2
As shown in table 2, for low-speed services such as FTP, since the system bandwidth actually configured by the terminal is 20MHz +20MHz, that is, downlink CA, although the Modulation and Coding Scheme (MCS) of scheduling is small, the power consumption of most link resources is still large. It can be seen that, under the bandwidth configuration of a single Control & Communication Link (CC-Link) system of 5G with 100MHz, 200MHz, 400MHz, etc., even if only a small amount of data is dynamically scheduled, the power consumption is still larger, and the endurance time is shortened, which is very difficult for operators to accept. Therefore, the terminal is inevitably required to have a power consumption saving scheme, and 5G is required to reduce the power consumption to a power consumption level close to 4G under the condition of the same rate requirement even if the system bandwidth is configured in a large scale.
Currently, some LTE terminals have some power consumption saving schemes, And besides a conventional Dynamic Voltage And Frequency Scaling (DVFS) scheme, a Core processor Sleep (Core Sleep) scheme, an Accelerator Sleep (Accelerator Sleep) scheme, a Timer Cut Off (Timer Cut Off) scheme, And the like, the LTE scheme selects whether to turn Off radio Frequency And operation of a part of baseband components based on a resolution result of a Physical Downlink Control Channel (PDCCH) is provided.
However, in the prior art, only power consumption saving strategies in the LTE network are provided, and all power consumption saving strategies in LTE are not completely applicable to 5G, so how to reduce power consumption of a terminal in a 5G communication system is still a difficult problem to be solved.
In order to solve the above problems, in the embodiments of the present invention, when it is determined that the service to be processed does not need to receive or send data in a certain communication interval, the radio frequency-baseband interface is correspondingly controlled to be turned off, and since power consumption caused by the radio frequency-baseband interface in the 5G communication system is very large, power consumption of the terminal can be greatly reduced.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention comprehensible, specific embodiments accompanied with figures are described in detail below.
Fig. 1 illustrates a circuit control method of a terminal in an embodiment of the present invention, where the circuit may include: a radio frequency-baseband interface. Referring now to fig. 1, the method is described in detail in sub-steps, which may include the steps of:
step S11: and judging the type of the service to be processed of each communication interval and the state of transmitting and receiving data in the communication interval according to the dynamic scheduling parameter and the static scheduling parameter of the network.
In a specific implementation, the communication interval may be a unit of measure for measuring a communication market, and specifically may include one or more of the following: scheduling interval, transmission time interval, or subframe. The skilled person can set the communication interval to other forms according to the actual needs. Therefore, the type of the service to be processed of each communication interval and the state of transmitting and receiving data in the communication interval are determined according to the dynamic scheduling parameter and the static scheduling parameter of the network, in other words, it can be analyzed which scheduling intervals (slots) or Transmission Time Intervals (TTIs) or subframes are not required to receive and/or transmit data according to the dynamic scheduling parameter and the static scheduling parameter of the network in the 5G connection state for the terminal.
In a specific implementation, the types of the to-be-processed traffic of the communication interval and the states of transceiving data in the communication interval may specifically include multiple types. For example, the type of the pending traffic may be static traffic, and no data needs to be received or transmitted during the communication interval. For another example, the types of the traffic to be processed may include dynamic traffic and static traffic, and only downlink data needs to be received in the communication interval. For another example, the types of the to-be-processed traffic may include dynamic traffic and static traffic, and only uplink data needs to be sent in the communication interval.
In an embodiment of the present invention, the pending traffic type of the communication interval may further include: and (4) dynamic service. Meanwhile, the state of transmitting and receiving data in the communication interval may further include no downlink and/or uplink dynamic scheduling in the communication interval.
In addition, in the specific implementation, if the type of the service to be processed in the communication interval is a dynamic service, in order to further reduce power consumption in a targeted manner, reference signal energy, control channel signal energy, a control channel decoding result and a false detection phenomenon may be comprehensively considered to perform power consumption saving operation. Specifically, the terminal may further determine whether at least one of the following parameters satisfies a corresponding preset condition: and referring to signal energy or noise power or a control channel decoding result or a false detection result, and simultaneously judging whether necessary data needs to be received according to a terminal self algorithm, wherein when the at least one parameter is determined to meet the corresponding preset condition and the terminal self algorithm is determined not to need to receive the necessary data, the operation of correspondingly controlling the radio frequency-baseband interface to be closed can be executed.
In other words, for a slot or TTI or subframe that needs to receive information related to a dynamic scheduling control channel, if it is determined that at least one of the following conditions is satisfied in the slot or TTI or subframe, the corresponding rf-baseband interface may be turned off: 1) the power of the Reference Signal (RS) used for channel estimation is low; 2) the interference is extremely large, the channel estimation noise is extremely large, and the specific appropriate threshold parameter can be determined according to the comprehensive simulation of terminal flexibility, anti-interference capability, decoding capability and the like); 3) all PDCCH signal energy is very small in the blind detection process, namely all PDCCH Search spaces (Search spaces) have very small signal energy; 4) in the blind detection process, all Cyclic Redundancy Check (CRC) results analyzed by the PDCCH are errors (error); 5) all PDCCH analysis results that CRC passes (i.e., OK) are illegal through parameter check.
In a specific implementation, the radio-frequency-baseband interface (RF-BB interface) may be an analog interface or a digital interface, and the radio-frequency-baseband interface may include a radio-frequency-baseband receiving interface (RF-BB RX interface) and a radio-frequency-baseband transmitting interface (RF-BB TX interface). The rf-baseband receiving interface may be one or more, one or more groups, and the rf-baseband transmitting interface may also be one or more, one or more groups.
When the pending traffic does not need to receive or send data in the communication interval, performing step S12; otherwise, the process continues to step S11.
Step S12: and correspondingly controlling the radio frequency-baseband interface to be closed.
Through a lot of experiments and researches, the inventor finds that the power consumption of a radio frequency-baseband interface (RF-BB interface) is necessarily a large power consumption source due to the use of a large bandwidth in 5G. Specifically, reference may be made to the simulation data shown in table 3, where table 3 is as follows:
TABLE 3
Referring to fig. 3, according to the operation mode that is common in the communication industry, that is, using a Low Voltage Differential Signaling (LVDS) interface, even if a very good 12nm, 28nm technology is adopted, in order to support a system bandwidth of 400MHz of millimeter wave (mmWave), power consumption of about 400mW is required, and if a battery Voltage with a size of 3.6V is used, power consumption of 100mA is required due to an RF-BB interface, which is unacceptable for a handheld device.
Therefore, in the embodiment of the present invention, the 5G high-power RF-BB interface is considered in combination, and different power-saving strategies are adopted for the specific Subcarrier Spacing (SCS), TTI, slot or mini-slot of 5G and resource element mapping (re-mapping) manner of 5G, that is, when the service to be processed does not need to receive or transmit data in the communication interval, the radio frequency-baseband interface is correspondingly controlled to be closed, so that the power consumption of the terminal can be greatly reduced.
In a specific implementation, when the service to be processed does not need to receive or send data in the communication interval, the channel corresponding to the state of receiving and sending data may be further controlled to be closed, and the peripheral device corresponding to the state of receiving and sending data may be controlled to be closed, so that power consumption of the peripheral device may be reduced, and power consumption of the terminal may be further reduced.
In detail, control of the channel and the peripheral device can be handled according to the traffic and the state of the transmission/reception data. For example, when the type of the service to be processed is a static service and no data needs to be received or transmitted in the communication interval, the radio frequency downlink channel and/or the radio frequency uplink channel may be controlled to be closed, and the low noise amplifier and/or the power amplifier at the radio frequency front end may be controlled to be closed. When the type of the service to be processed is a dynamic service and no downlink and/or uplink dynamic scheduling exists in the communication interval, and data does not need to be received and/or transmitted, the radio frequency downlink channel and/or uplink channel can be controlled to be closed, and a low noise amplifier and/or a power amplifier at the radio frequency front end are controlled to be closed. And when the types of the services to be processed comprise dynamic services and static services, and only downlink data needs to be received in the communication interval, the radio frequency uplink channel can be controlled to be closed, and the radio frequency front end uplink related power amplifier is controlled to be closed. And when the type of the service to be processed comprises a dynamic service and a static service and only uplink data needs to be sent in the communication interval, the radio frequency downlink channel can be controlled to be closed, and the radio frequency front end downlink related low noise amplifier is controlled to be closed.
In order to further reduce power consumption, in a specific implementation, when the service to be processed does not need to receive or send data in the communication interval, whether to control the phase-locked loop corresponding to the radio frequency-baseband interface to be closed may be determined according to a subcarrier interval, a scheduling interval, a resource element mapping manner, a reference signal, and a time length required for related communication configured in the current 5G, and when it is determined that to control the phase-locked loop corresponding to the radio frequency-baseband interface to be closed, the phase-locked loop corresponding to the radio frequency-baseband interface is controlled to be closed.
In a specific implementation, whether to turn off only the rf-baseband interface internal data transmission and reception processing or to turn off the transmission Phase-Locked Loop and/or the reception Phase-Locked Loop depending on the PLL (Phase Locked Loop) and the interface at the same time may be determined according to the Subcarrier Spacing (SCS) of the current 5G configuration, the size of the sub-frame (Slot)/micro-sub-frame (mini-Slot), the resource element mapping (in a manner of measuring the required reference signal, the interrupt duration (interrupt) allowed by the protocol and the duration without terminal data processing, the Phase-Locked Loop or Phase-Locked Loop (PLL) of the transceiver (TX/RX), and the total duration required for the PLL (PLL) to turn on, set, calibrate and synchronize, etc., wherein the Subcarrier Spacing may range from 15khz, 30khz, 60khz … to 240khz, the manner of resource element mapping may include time domain first and frequency domain first.
For ease of understanding and explanation, fig. 2 is a timing diagram of a communication interval in a 5G communication system in an embodiment of the present invention, and in fig. 2, a time period t0-t1 is one TTI; the time period t1-t4 is a TTI, the terminal only needs to receive data and does not send data, and the terminal can judge whether the current TTI has downlink scheduling based on various conditions, and if not, the terminal can control to close the downlink reception of the radio frequency and the baseband and close the radio frequency-baseband interface and the phase-locked loop; the time period is one TTI, and during t4-t5, the terminal does not receive data nor transmit data; the time period t5-t6 is one TTI, and during the period t5-t6, the terminal only needs to receive data and does not transmit data. During the time period t0-t1, the terminal neither receives nor transmits data. In the time period t1-t2, the terminal performs the detection process of the PDCCH. During the time period t2-t3, the terminal enters a sleep state. In the time period t3-t4, the terminal can configure the radio frequency working parameters of the next TTI, the mode of the radio frequency-baseband interface and the phase-locked loop, and the initialization, calibration and synchronous stabilization time of the radio frequency and the interface after the configuration is completed.
Referring to fig. 2, for a typical 5G terminal, when operating on a 5G link with TTI of about 140us, PDCCH occupies two characters (symbols) and has a length of about 70us, if the conditions for turning off the rf path according to the above-mentioned types are satisfied, and for the next communication interval, if the condition that the phase-locked loop and the related PLL can be turned on to be stable and often t is less than x, the phase-locked loop and PLL can be turned off, otherwise the phase-locked loop and PLL can not be turned off. Wherein, x can be 70us, and the smaller the value of x is, the better, the smaller the power consumption can be, the more, correspondingly, want to do the smaller, the higher the difficult requirement to the radio frequency design is also.
