Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

As with conventional communications, the network coverage of a zero power consumption communications network is limited by many aspects of the network device transmit power, operating frequency band, device antenna gain, and device receiver sensitivity. Furthermore, it is particularly pointed out that the coverage of a zero-power communication network is closely related to the power level of the wireless powering signal. The zero-power consumption communication system has a plurality of communication modes, one of which is that the base station provides wireless energy supply and sends trigger signaling to the zero-power consumption terminal, the backscattering signal of the zero-power consumption terminal is received by the intelligent terminal, and the intelligent terminal sends air interface data to the base station.

The energy of the energy supply signal required by the zero-power consumption terminal to wake up is required to meet a certain requirement, but the radiation energy of the base station signal is limited, and the zero-power consumption terminal does not need to wake up at any moment, so that the base station needs to negotiate with the relay terminal, and proper energy supply signal emission energy, time length and period are selected.

In order to achieve the objective, the present application provides a relay-based zero-power consumption terminal wake-up communication mechanism, in which, in a communication mode that a base station provides wireless energy supply and trigger signaling for a zero-power consumption terminal in a zero-power consumption communication system, the relay terminal reports a current channel environment and a required zero-power consumption terminal wake-up period to a network, and the base station determines energy supply signal energy of the base station, a transmission duration period and the like according to the channel environment reported by the relay terminal and the required zero-power consumption terminal wake-up information, so that the zero-power consumption terminal can be timely awakened according to the requirements, and extra resource waste is avoided.

The energy supply method of the zero-power-consumption terminal can be applied to an application environment shown in fig. 1. The relay terminal 102 communicates with the base station 104 through a network and communicates with the zero-power-consumption terminal 106, where the relay terminal 102 is located near the zero-power-consumption terminal 106, and the number of the zero-power-consumption terminals 106 is plural, and the base station 104 supplies power to the zero-power-consumption terminal 106, which generally supplies power to one zero-power-consumption terminal. Specifically, after the relay terminal 102 accesses the base station 104, wake-up requirement information of the zero-power consumption terminal 106 is sent to the base station 104, after the base station 104 receives the wake-up requirement information, a channel state acquisition instruction is sent to the relay terminal 102, the relay terminal 102 measures a measurement signal carried by the channel state acquisition instruction to obtain self channel state information, and the channel state information is returned to the base station 104. The base station 104 determines the power supply configuration parameters for the zero-power consumption terminal 106 based on the channel state information of the relay terminal 102, and transmits a corresponding power supply signal to the zero-power consumption terminal 106 according to the power supply configuration parameters, so that the power supply signal supplies power to the zero-power consumption terminal 106.

In one embodiment, as shown in fig. 2, a method for powering a terminal with zero power consumption is provided, and the method is applied to the base station 104 in fig. 1 for illustration, and includes the following steps:

step S210, when the wake-up request information of the zero power consumption terminal sent by the relay terminal is received, a channel state acquisition instruction is sent to the relay terminal.

The wake-up requirement information comprises target energy and target power required for waking up the zero-power-consumption terminal.

Wherein the number of the zero-power-consumption terminals is a plurality of.

Specifically, after the relay terminal is accessed to the base station, the information of the zero-power-consumption terminals which are the relay terminal and need to be awakened is firstly reported to the base station, and then the awakening requirement information of the zero-power-consumption terminals around the relay terminal is reported to the base station. In one embodiment, the relay terminal may also report the information of the zero power consumption terminal that needs to wake up and the wake-up requirement information of the zero power consumption terminal around the relay terminal to the base station at the same time, so as to ensure that the identity of the relay terminal can be confirmed when the base station receives the wake-up requirement information. After receiving the wake-up requirement information of the zero-power consumption terminal sent by the relay terminal, the base station can send a channel state acquisition instruction carrying a measurement signal to the relay terminal. In this step, the relay terminal may determine wake-up requirement information of the zero power consumption terminal based on the type of the zero power consumption terminal.

Step S220, receiving channel state information of the relay terminal returned by the relay terminal based on the channel state acquisition instruction; the channel state information is obtained by measuring a measurement signal carried by the channel state acquisition instruction by the relay terminal.

The channel state information may include RSRP (Reference Signal Receiving Power, reference signal received power), SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio, i.e., signal to noise ratio) of the relay terminal, and the like.

In a specific implementation, when the base station sends an information state acquisition instruction to the relay terminal, the base station sends a measurement signal to the relay terminal at the same time, that is, the channel state acquisition instruction can carry the measurement signal, and the relay terminal can obtain the channel state information of itself by measuring the measurement signal, and then returns the channel state to the base station, so that the base station receives the channel state information of the relay terminal and then carries out subsequent processing.

Step S230, determining energy supply configuration parameters for the zero power consumption terminal based on the channel state information and the wake-up requirement information.

The energy supply configuration parameters can comprise signal transmission power, signal transmission duration and signal transmission period.

Specifically, since the signal is lost during transmission, when determining the power supply configuration parameter for the zero-power consumption terminal, in addition to the wake-up requirement information of the zero-power consumption terminal itself, the lost energy of the power supply signal transmitted from the base station to the zero-power consumption terminal needs to be considered, and the lost energy can be determined through the channel state information. It can be understood that, because the construction of the zero-power-consumption terminal is too simple to report the channel state information to the base station, and the position of the relay terminal is near the zero-power-consumption terminal, the present application calculates the path loss energy when the functional signal is transmitted to the zero-power-consumption terminal by taking the channel state information of the relay terminal near the zero-power-consumption terminal as a reference, and further determines the energy supply configuration parameter for the zero-power-consumption terminal based on the path loss energy and the wake-up requirement information of the zero-power-consumption terminal.

Step S240, corresponding energy supply signals are transmitted to the zero-power consumption terminal according to the energy supply configuration parameters; the power supply signal is used for supplying power to the zero-power consumption terminal.

In the specific implementation, after determining the energy supply configuration parameters including the signal transmission power, the signal transmission duration and the signal transmission period, the base station can periodically send energy supply signals corresponding to the signal transmission power and the signal transmission duration to the zero-power consumption terminal according to the signal transmission period, so that the zero-power consumption terminal can acquire energy from the energy supply signals to perform communication.

In one embodiment, the base station may acquire its channel state information from the relay terminal each time before transmitting the functional signal to the zero power consumption terminal, so as to determine the transmission power and the transmission duration of the functional signal.

In the energy supply method of the zero-power-consumption terminal, when the base station receives the wake-up demand information of the zero-power-consumption terminal sent by the relay terminal, the base station sends a channel state acquisition instruction to the relay terminal, so that the relay terminal returns channel state information of the relay terminal to the base station based on the channel state acquisition instruction; the base station further determines energy supply configuration parameters aiming at the zero-power consumption terminal based on the channel state information and the wake-up demand information; and transmitting a corresponding energy supply signal to the zero-power-consumption terminal according to the energy supply configuration parameters, and supplying energy to the zero-power-consumption terminal. In the method, the relay terminal is used as a manager role to communicate between the base station and the zero-power-consumption terminal, so that the energy supply signal transmitted by the base station to the zero-power-consumption terminal can be obtained based on the wake-up demand information of the zero-power-consumption terminal, different energy supply signals can be configured according to the demands of different zero-power-consumption terminals, the energy supply flexibility is improved, and meanwhile, the energy supply signal is transmitted based on the wake-up demand information of the zero-power-consumption terminal, the energy supply signal can be prevented from being transmitted when the zero-power-consumption terminal does not need to be awakened, and the extra resource waste is reduced.

In an exemplary embodiment, the wake-up requirement information carries a target energy and a target power required for waking up the zero power consumption terminal;

as shown in fig. 3, in the above step S230, based on the channel state information and the wake-up requirement information, the determining of the power supply configuration parameters for the zero power consumption terminal may be specifically implemented by the following steps:

step S231, determining path loss energy in the process of transmitting the energy supply signal from the base station to the zero-power consumption terminal based on the channel state information;

step S232, determining signal transmission power and signal transmission duration aiming at a zero-power-consumption terminal based on the path loss energy, the target energy and the target power;

step S233, the signal transmission power and the signal transmission duration are used as energy supply configuration parameters for the zero-power consumption terminal.

In the specific implementation, the base station can calculate the path loss energy in the process that the energy supply signal reaches the relay terminal from the base station based on the channel state information of the relay terminal, and the relay terminal is near the zero-power-consumption terminal, so that the path loss energy can be used as the path loss energy in the process that the energy supply signal is transmitted to the zero-power-consumption terminal from the base station. The energy actually required to be transmitted by the base station, namely the signal transmission energy aiming at the zero-power-consumption terminal, can be further calculated based on the path loss energy and the target energy, and the signal transmission power and the signal transmission duration aiming at the zero-power-consumption terminal are determined according to the signal transmission energy and the target power and are used as energy supply configuration parameters aiming at the zero-power-consumption terminal.

In this embodiment, the channel state information of the relay terminal is used to determine the path loss energy in the process of transmitting the energy supply signal from the base station to the zero-power-consumption terminal, and further combine the path loss energy with the target energy and the target power actually required by the zero-power-consumption terminal to determine the signal transmitting power and the signal transmitting duration for the zero-power-consumption terminal.

In an exemplary embodiment, in the step S232, determining the signal transmission power and the signal transmission duration for the zero-power terminal based on the path loss energy, the target energy and the target power includes: the method comprises the steps of summing the path loss energy and target energy to obtain signal emission energy aiming at a zero-power-consumption terminal; and taking the target power as the signal transmission power for the zero-power-consumption terminal, and determining the signal transmission duration for the zero-power-consumption terminal based on the signal transmission energy and the target power.

In a specific implementation, in order to ensure that the energy reaching the zero-power-consumption terminal meets the requirement of the zero-power-consumption terminal, after the path loss energy is determined, the path loss energy can be added with the target energy actually required by the zero-power-consumption terminal to obtain the signal transmission energy of the base station, further, the signal transmission energy is obtained by multiplying the transmission power and the transmission time, in order to meet the power requirement of the zero-power-consumption terminal, the target power of the zero-power-consumption terminal can be used as the signal transmission power of the base station, then the signal transmission energy is divided with the target power, and the obtained result is used as the signal transmission duration aiming at the zero-power-consumption terminal.

In this embodiment, the path loss energy and the target energy are summed to obtain the signal transmission energy for the zero-power-consumption terminal, the target power is used as the signal transmission power for the zero-power-consumption terminal, and the signal transmission duration for the zero-power-consumption terminal is determined based on the signal transmission energy and the target power, so that it is ensured that the energy supply signal reaching the zero-power-consumption terminal can simultaneously meet the energy requirement and the power requirement of the zero-power-consumption terminal.

In an exemplary embodiment, after determining the signal transmission power and the signal transmission duration for the zero-power consumption terminal in step S232 based on the path loss energy, the target energy, and the target power, the method further includes:

step S233, acquiring a transmitting power threshold of a base station;

step S234, if the signal transmitting power is larger than the transmitting power threshold, the transmitting power threshold is used as the signal transmitting power for the zero-power-consumption terminal; and determining a new signal transmission duration based on the signal transmission energy and the transmission power threshold value as the signal transmission duration for the zero-power-consumption terminal.

In a specific implementation, energy of an energy supply signal required by waking up a zero-power consumption terminal needs to meet a certain requirement, but radiation energy of a base station signal is limited, so that a transmitting power threshold of a base station needs to be considered when determining energy supply configuration parameters for the zero-power consumption terminal.

More specifically, after determining the signal transmission power and the signal transmission duration for the zero-power terminal based on the path loss energy, the target energy and the target power, the determined signal transmission power and the transmission power threshold of the base station may be compared, and if the signal transmission power is smaller than the transmission power threshold, the determined signal transmission power and the determined signal transmission duration may be directly used as energy supply configuration parameters for the zero-power terminal without processing. If the signal transmission power is larger than the transmission power threshold, the transmission power threshold is used as the signal transmission power for the zero-power-consumption terminal if the signal transmission power exceeds the radiation energy upper limit of the base station, and the signal transmission time length can be correspondingly increased to determine the new signal transmission time length in order to ensure that the signal transmission energy is unchanged. In particular, the new signal transmission duration may be obtained by dividing the signal transmission energy by the transmission power threshold.

In this embodiment, when the signal transmission power is greater than the transmission power threshold, the transmission power threshold is used as the signal transmission power for the zero-power terminal, and the new signal transmission duration is determined based on the signal transmission energy and the transmission power threshold and used as the signal transmission duration for the zero-power terminal, so that the energy supply configuration parameter for the zero-power terminal also meets the radiation energy requirement of the base station under the condition of ensuring the energy supply requirement of the zero-power terminal.

In an exemplary embodiment, step S233 further includes, before using the signal transmission power and the signal transmission duration as the power supply configuration parameters for the zero-power terminal: determining whether the wake-up requirement information comprises a wake-up period of the zero-power consumption terminal;

step S233 further includes: if the wake-up demand information comprises a wake-up period, the signal transmitting power, the signal transmitting duration and the wake-up period are used as energy supply configuration parameters for the zero-power consumption terminal; if the wake-up demand information does not include the wake-up period, acquiring a preset period; and jointly using the signal transmitting power, the signal transmitting duration and the preset period as energy supply configuration parameters for the zero-power-consumption terminal.

In a specific implementation, the zero-power consumption terminal is not in the wake-up state at any moment, that is, the zero-power consumption terminal can have a wake-up period, and the relay terminal can simultaneously package the wake-up period in the wake-up requirement information and send the wake-up requirement information to the base station when sending the wake-up requirement information of the zero-power consumption terminal. Therefore, when determining the energy supply configuration parameters for the zero-power consumption terminal, the base station can also determine whether the wake-up requirement information comprises a wake-up period, and if so, the determined signal transmitting power, the determined signal transmitting time length and the wake-up period are used as the energy supply configuration parameters for the zero-power consumption terminal. If the power consumption of the zero-power consumption terminal is not greater than the preset power consumption of the zero-power consumption terminal, the base station can acquire a preset default period as the preset period, and the signal transmitting power, the signal transmitting duration and the preset period are used as energy supply configuration parameters for the zero-power consumption terminal.

When the wake-up requirement information comprises a wake-up period, the signal transmitting power, the signal transmitting duration and the wake-up period are used as energy supply configuration parameters for the zero-power consumption terminal; when the wake-up demand information does not comprise a wake-up period, acquiring a preset period; and jointly using the signal transmitting power, the signal transmitting duration and the preset period as energy supply configuration parameters for the zero-power-consumption terminal. Therefore, the energy supply signal is periodically transmitted without being transmitted from time to time, the energy supply signal is prevented from being transmitted when the zero-power consumption terminal does not need to be awakened, and the extra resource waste is reduced.

In an exemplary embodiment, the number of zero power terminals is plural; after transmitting the corresponding energy supply signal to the zero-power consumption terminal according to the energy supply configuration parameters in step S240, the method further includes:

step S241, receiving feedback information sent by a relay terminal and aiming at each zero-power consumption terminal; the feedback information represents the wake-up result of the zero-power consumption terminal;

in step S242, in the case where it is determined that there is a zero power consumption terminal that has not been awakened based on the feedback information, an energizing signal is again transmitted to the zero power consumption terminal.

It will be appreciated that the power supply signal transmitted by the base station is typically a zero-power consumption terminal facing an area, so there are a plurality of zero-power consumption terminals, and the distance between the zero-power consumption terminals and the base station is near or far, while the relay terminal may be located at a position near to the base station, so the power supply configuration parameters determined based on the channel state information of the relay terminal may not be accurate, so that in the coverage area of the power supply signal of the base station, some zero-power consumption terminals far away may not be awakened due to insufficient energy, and in this case, the base station needs to transmit the power supply signal again.

In the specific implementation, after the zero-power-consumption terminal receives the energy supply signal transmitted by the base station and is awakened, the zero-power-consumption terminal transmits information to the relay terminal, and the zero-power-consumption terminal which is not awakened does not transmit information to the relay terminal, so that the relay terminal can determine whether all the zero-power-consumption terminals are awakened according to the received information of the zero-power-consumption terminal, and further can send feedback information representing the awakening result of the zero-power-consumption terminal to the base station. After receiving the feedback information, the base station determines whether an energy supply signal needs to be added according to the feedback information so as to wake up all the zero-power consumption terminals. Specifically, if all the zero-power terminals are determined to be awakened based on the feedback information, the retransmission of the functional signals is not needed; otherwise, if the fact that the non-awakened zero-power-consumption terminal exists is determined based on the feedback information, the fact that the energy supply signal needs to be added is determined, and the energy supply signal is sent to the zero-power-consumption terminal again.

In this embodiment, after transmitting the power supply signal to the zero-power consumption terminals, the relay terminal also transmits the wake-up result of each zero-power consumption terminal to the base station, so that the base station transmits the power supply signal to the zero-power consumption terminals again under the condition that there are non-wake-up zero-power consumption terminals, so as to ensure that all the zero-power consumption terminals are wake-up.

Further, in an exemplary embodiment, the energy supply configuration parameters include a signal transmission power and a signal transmission duration;

in the case that it is determined that there is a zero power consumption terminal that is not awakened based on the feedback information, the step S242 may be implemented by transmitting the power supply signal to the zero power consumption terminal again, which is specifically:

step S242a, under the condition that the non-awakened zero-power consumption terminal exists based on the feedback information, acquiring signal transmitting power and signal transmitting duration corresponding to the energy supply signal transmitted by the base station last time, and acquiring a transmitting power threshold of the base station;

step S242b, if the signal transmitting power transmitted last time does not reach the transmitting power threshold, transmitting an energy supply signal to the zero-power-consumption terminal again after increasing the signal transmitting power;

in step S242c, if the signal transmission power of the last transmission has reached the transmission power threshold, the energy supply signal is transmitted again to the zero power consumption terminal after the signal transmission duration is increased.

In a specific implementation, when the base station determines that the zero-power consumption terminal which is not awakened exists based on the feedback information of the relay terminal, the base station indicates that the energy of the energy supply signal is insufficient, so that after the energy supply signal is required to be added, the energy supply signal is transmitted to the zero-power consumption terminal again, and the energy supply signal adding strategy is as follows: and preferentially increasing the signal transmission power, and increasing the signal transmission duration when the signal transmission power reaches the transmission power threshold of the base station. Therefore, before transmitting the energy supply signal again, the signal transmitting power and the signal transmitting time length corresponding to the energy supply signal transmitted by the base station last time need to be acquired, the transmitting power threshold of the base station is acquired, and the signal transmitting power of the last time is compared with the transmitting power threshold of the base station. If the signal transmitting power transmitted last time does not reach the transmitting power threshold, the signal transmitting power is increased, the signal transmitting time is not increased, and an energy supply signal is transmitted to the zero-power-consumption terminal again; if the signal transmitting power transmitted last time reaches the transmitting power threshold, transmitting an energy supply signal to the zero-power-consumption terminal again after the signal transmitting time length is increased.

In this embodiment, under the condition that it is determined that there is an unstacked zero-power consumption terminal based on feedback information, signal transmission power is preferentially increased, and when the signal transmission power reaches a transmission power threshold of a base station, a method for increasing signal transmission duration increases signal transmission energy, and wakes up all zero-power consumption terminals.

In one embodiment, as shown in fig. 4, a method for powering a terminal with zero power consumption is provided, and the method is applied to the relay terminal 102 in fig. 1 for illustration, and includes the following steps:

step S410, wake-up requirement information of a zero-power consumption terminal near the relay terminal is obtained, and the wake-up requirement information is sent to the base station.

In a specific implementation, the relay terminal can determine the wake-up requirement information of the zero-power-consumption terminals based on the types of the zero-power-consumption terminals positioned nearby the relay terminal, and further after the relay terminal is accessed to the base station, the relay terminal can report the information of the zero-power-consumption terminals which are the relay terminal and are required to be wake-up to the base station, and then report the wake-up requirement information of the zero-power-consumption terminals around the relay terminal to the base station. In one embodiment, the relay terminal may also report the information of the zero power consumption terminal that needs to wake up and the wake-up requirement information of the zero power consumption terminal around the relay terminal to the base station at the same time, so as to ensure that the identity of the relay terminal can be confirmed when the base station receives the wake-up requirement information.

Step S420, receiving a channel state acquisition instruction returned by the base station after receiving the wake-up demand information.

In a specific implementation, after receiving wake-up requirement information of a zero-power consumption terminal sent by a relay terminal, a base station sends a channel state acquisition instruction carrying a measurement signal to the relay terminal so that the relay terminal can measure a channel environment according to the channel state acquisition instruction.

Step S430, measuring the measurement signal carried by the channel state acquisition instruction to obtain the channel state information of the relay terminal.

In a specific implementation, the relay terminal measures the measurement signal to obtain channel state information such as RSRP (Reference Signal Receiving Power, reference signal received power), SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio, i.e. signal to noise ratio), and the like.

Step S440, returning channel state information to the base station; the base station is used for determining energy supply configuration parameters aiming at the zero-power consumption terminal based on the channel state information and the wake-up demand information, and transmitting corresponding energy supply signals to the zero-power consumption terminal according to the energy supply configuration parameters.

In a specific implementation, after obtaining the channel state information of the relay terminal, the relay terminal can return the channel state information to the base station, so that the base station receives the channel state information of the relay terminal and then performs subsequent processing. Specifically, the base station may determine an energy supply configuration parameter for the zero-power consumption terminal based on the channel state information and the wake-up requirement information, and transmit a corresponding energy supply signal to the zero-power consumption terminal according to the energy supply configuration parameter, so that the zero-power consumption terminal may acquire energy from the energy supply signal to perform communication.

In the energy supply method of the zero-power consumption terminal, the relay terminal sends the acquired wake-up demand information of the zero-power consumption terminal positioned nearby the relay terminal to the base station, measures the measurement signal carried by the channel state acquisition instruction returned by the base station after receiving the wake-up demand information to obtain the channel state information of the relay terminal, and returns the channel state information to the base station, so that the base station can determine the energy supply configuration parameters for the zero-power consumption terminal based on the channel state information and the wake-up demand information, and transmits the corresponding energy supply signals to the zero-power consumption terminal according to the energy supply configuration parameters. In the method, the relay terminal is used as a manager role to communicate between the base station and the zero-power-consumption terminal, so that the energy supply signal transmitted by the base station to the zero-power-consumption terminal can be obtained based on the wake-up demand information of the zero-power-consumption terminal, different energy supply signals can be configured according to the demands of different zero-power-consumption terminals, the energy supply flexibility is improved, and meanwhile, the energy supply signal is transmitted based on the wake-up demand information of the zero-power-consumption terminal, the energy supply signal can be prevented from being transmitted when the zero-power-consumption terminal does not need to be awakened, and the extra resource waste is reduced.

It should be noted that, the power supply method of the zero power consumption terminal applied to the relay terminal provided in this embodiment corresponds to the power supply method of the zero power consumption terminal applied to the base station, so each embodiment of the power supply method of the zero power consumption terminal applied to the base station may have a corresponding implementation scheme in this embodiment, which is not described herein again.

S7: the zero power consumption terminal is awakened and transmits information to the relay terminal.

S8: and the relay terminal confirms whether all the zero-power-consumption terminals are awakened according to the received information transmitted by the zero-power-consumption terminals.

S8-1: if all the zero-power-consumption terminals are awakened, reporting that all the zero-power-consumption terminals of the base station are awakened, and waiting for the next awakening period to transmit an energy supply signal by the base station.

S8-2: if the zero power consumption terminal is not awakened, the relay terminal reports that the base station has zero power consumption terminals which are not awakened, the base station increases energy of the energy supply signal to send the energy supply signal again until the relay terminal reports that all the zero power consumption terminals are awakened.

According to the method provided by the embodiment, based on the relay zero-power consumption terminal awakening communication mechanism, under the communication mode that the base station provides wireless energy supply and trigger signaling for the zero-power consumption terminal in the zero-power consumption communication system, the relay terminal reports the current channel environment and the required zero-power consumption terminal awakening demand information to the network, and the base station determines the energy of the base station energy supply signal, the period of the transmitting duration and the like according to the channel environment information and the awakening demand information reported by the relay terminal, so that the zero-power consumption terminal can be awakened timely according to the demand, the functional flexibility is improved, and extra resource waste can be avoided.
