Detailed Description
Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that: the relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present disclosure unless specifically stated otherwise.
Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description.
The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail, but are intended to be part of the specification where appropriate.
In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.
As mentioned above, the base station transmit antenna is turned off in the time domain by turning off the base station symbol, so that the power consumption of the PA can be reduced. When the network is in a medium-low load state, because more spare time resources exist, the energy consumption can be greatly reduced, so that the operation cost of an NR (New Radio) network is reduced, and the landing and the development of 5G are promoted.
However, due to the influence of the power amplifier characteristics, the PA power needs a certain time to switch, and the symbol turn-off cannot be completed immediately. The NR network has a high requirement for network delay, so the utility of symbol turn-off is affected; moreover, the base station turning on the symbol off directly may not be able to meet the current network service requirements.
In view of the above technical problems, the technical scheme of the present disclosure can improve the efficiency of symbol turn-off, make it more practical, and can satisfy the requirements of the current network state as much as possible, thereby effectively improving the energy saving level of the base station.
For example, the present disclosure pre-configures a network energy saving mode and flexibly triggers the network energy saving mode, thereby shortening the configuration time of network energy saving, enabling symbol turn-off to better adapt to an NR network, and effectively reducing the energy consumption of an AAU (Active Antenna Unit) and further reducing the energy consumption of a base station. Therefore, the operation cost of the NR network is effectively reduced.
For example, the technical solution of the present disclosure can be realized by the following embodiments.
Fig. 1 shows a flow chart of some embodiments of a method of power saving for a base station of the present disclosure.
As shown in fig. 1, in step 110, a current symbol-off mode is configured for the base station according to current traffic demands.
For example, in case it is detected that the load of the current cell network is below a load threshold, the current symbol-off mode is configured for the base station.
In some embodiments, step 110 may be implemented in accordance with the embodiment in FIG. 2.
Fig. 2 shows a flow chart of some embodiments of step 110 of the present disclosure.
As shown in FIG. 2, step 210 may be performed prior to step 110.
In step 210, a plurality of symbol off modes are preconfigured according to different traffic requirements, different symbol off modes having at least one of different PA power at off, different off periods, or different consecutive symbol lengths at on.
In some embodiments, a plurality of symbol off modes are preconfigured according to at least one of different traffic throughput requirements or different latency requirements.
For example, a first symbol turn-off mode is configured according to a first delay requirement, a second symbol turn-off mode is configured according to a second delay requirement, the delay of the first delay requirement is longer than the delay of the second delay requirement, and the PA power at the turn-off of the first symbol turn-off mode is lower than the PA power at the turn-off of the symbol turn-off mode.
For example, the base station pre-configures a plurality of symbol off-modes, and when it is detected that the network load of the current cell is low, the core network may pre-configure the current symbol off-mode of the base station through signaling.
In some embodiments, the main difference between the preconfigured different symbol off modes is: differential configuration for different traffic throughputs and delays.
For example, because the time required for adjusting the PA power is different, the PA power can be reduced to a very low level or even 0 level for the service with long delay requirement; for traffic with relatively low latency requirements, the PA power reduction may be reduced to ensure fast wake-up of the base station.
For example, the symbol-off mode may be configured by at least: PA power level at off, off period, and continuous symbol length at on, etc.
Step 110 may include step 1110. In step 1110, a current symbol-off mode is selected from a plurality of symbol-off modes according to current traffic demands.
Thus, by pre-configuring the symbol turn-off mode, time for configuring symbol turn-off is saved. Therefore, the efficiency of symbol turn-off configuration is effectively improved, and balance is found between the optimal performance and energy conservation.
After the current symbol turn-off mode is selected, the relevant information of the current symbol turn-off mode can be sent to the terminal through other steps in fig. 1; and the terminal judges whether to actively trigger the current symbol turn-off mode of the base station according to the received message.
In step 120, information related to the current symbol off mode is sent to the terminal.
In step 130, in the case of the first signaling returned by the terminal, it is determined whether to turn on the current symbol turn-off mode according to the indication of the first signaling.
In some embodiments, the first signaling instructs the base station to switch on the current symbol-off mode if at least one of the following conditions is met: the time delay required by the terminal is higher than a time delay threshold value; or the throughput required by the terminal is below a throughput threshold.
In some embodiments, the first signaling is triggered by an underlying signal. For example, the underlying signaling includes UCI and MAC CE information.
In some embodiments, the terminal triggers the current symbol off mode of the base station by means of the underlying signal. For example, when the terminal considers that the time delay required by the terminal is high and the throughput is low, the current symbol turn-off format configured for the base station can be triggered through signaling; the terminal may also inform the base station not to use the current symbol off mode. For example, it can be triggered by the following underlying signals: UCI and MAC CE.
In some embodiments, under the condition that the first signaling is not received within a preset time, measuring the current network environment; and judging whether to start the current symbol turn-off mode or not according to the measurement result. For example, the current symbol off mode is turned on in case the measurement result satisfies at least one of a condition that the stability index of the current network is above the stability threshold, or a condition that the load of the current network is below the load threshold.
For example, after the base station side pre-configures the current symbol turn-off mode, if the base station side fails to receive the trigger signaling from the terminal within a certain period, the base station may measure the network service; if the network environment is stable and the load is low, the current symbol off mode can be triggered by itself.
In some embodiments, in the case that the current symbol turn-off mode is turned on, the current symbol turn-off mode is stopped according to an indication of a second signaling returned by the terminal. For example, the second signaling is generated when the service provided by the network cannot meet the terminal requirement after the current symbol off mode is turned on.
In some embodiments, the current symbol turn-off mode is stopped according to the control of the network element on the network side which has received the second signaling; or receiving a second signaling sent by the bottom layer signaling, stopping the current symbol turn-off mode, and informing the network side that the current symbol turn-off mode is stopped by the high layer signaling.
For example, after the current symbol turn-off mode is adopted, if the terminal finds that the service provided by the current network is not enough to meet the service requirement of the terminal, the terminal may send a termination signaling to stop the current symbol turn-off mode.
For example, the termination signaling may be sent to the network side, and then the network element of the network side controls the base station to close the current symbol turn-off mode; the termination signaling can also be directly sent to the base station through the bottom layer signal, the base station immediately stops the current symbol turn-off mode, and the base station informs the decision to the network side through the high layer signaling.
In some embodiments, in the event that the current symbol-off mode is stopped, it is determined whether to reconfigure the current symbol-off mode for the base station based on the measured current network conditions.
For example, after knowing that the current symbol turn-off is turned off, the network side can determine whether to reselect the current symbol turn-off mode as the pre-configuration of the symbol turn-off mode for the network side according to the network measurement condition, and repeat steps 110 to 130.
In the above embodiment, the base station pre-configures a plurality of symbol turn-off modes, which can improve the configuration efficiency; the terminal triggers the base station to turn on or turn off the current symbol turn-off mode, so that the service quality of the network can be ensured to meet the requirements of users; when the terminal can not trigger the symbol turn-off (if the terminal does not support the function), the base station side can also trigger the symbol turn-off mode by self measurement, so that the forward compatibility is better and the realization is more flexible.
For a network scene with medium and low energy consumption, the energy consumption can be effectively reduced by more than 20% by adopting a symbol turn-off mode. On the basis, by adopting the technical scheme disclosed by the invention, the symbol turn-off efficiency can be improved, the practicability of symbol turn-off is effectively improved, more medium and low load networks can use the symbol turn-off mode, and the energy consumption is effectively reduced.
Fig. 3 shows a flow chart of further embodiments of a method of power saving for a base station of the present disclosure.
As shown in fig. 3, in step 310, a multi-level symbol-off pattern is predefined for the base station.
For example, the base station pre-configures a plurality of symbol off-modes, and when it is detected that the network load of the current cell is low, the core network may pre-configure the current symbol off-mode of the base station through signaling.
In some embodiments, the main difference between the preconfigured different symbol off modes is: differential configuration for different traffic throughputs and delays.
For example, because the time required for adjusting the PA power is different, for a service with a long delay requirement, the PA power can be reduced to a very low level or even 0 level; for traffic with relatively low latency requirements, the PA power reduction may be reduced to ensure fast wake-up of the base station.
For example, the symbol-off mode may be configured by at least: PA power level at off, off period, and continuous symbol length at on, etc.
Thus, by pre-configuring the symbol turn-off mode, time for configuring symbol turn-off is saved. Therefore, the efficiency of symbol turn-off configuration is effectively improved, and balance is found between the optimal performance and energy conservation.
In step 320, the network side detects the traffic demand and pre-configures the symbol off mode for the base station.
For example, the relevant information of the current symbol turn-off mode is sent to the terminal; and the terminal judges whether to actively trigger the current symbol turn-off mode of the base station according to the received message.
In step 330, the terminal determines whether to turn on the symbol-off mode. In case that the terminal turns on the symbol off mode, performing step 340; in case the terminal does not respond for a long time, step 350 is performed.
In some embodiments, the terminal triggers the current symbol off mode of the base station by means of the underlying signal. For example, when the terminal considers that the time delay required by the terminal is high and the throughput is low, the current symbol turn-off format configured for the base station can be triggered through signaling; the terminal may also inform the base station not to use the current symbol off mode. For example, it can be triggered by the following underlying signals: UCI and MAC CE.
In step 340, the base station turns on the symbol off mode.
In step 350, the base station determines whether to turn on the symbol-off mode. In case of power on, step 340 is performed; without turning on, it is re-executed from step 320.
For example, after the base station side pre-configures the current symbol turn-off mode, if the base station side fails to receive the trigger signaling from the terminal within a certain period, the base station may measure the network service; if the network environment is stable and the load is low, the current symbol off mode can be triggered by itself.
In step 360, the terminal determines whether to turn off the symbol off mode. In case of shutdown, re-execution starts from step 320; without shutdown, it is re-executed from step 340.
For example, after the current symbol turn-off mode is adopted, if the terminal finds that the service provided by the current network is not enough to meet the service requirement of the terminal, the terminal may send a termination signaling to stop the current symbol turn-off mode.
For example, the termination signaling may be sent to the network side, and then the network element of the network side controls the base station to close the current symbol turn-off mode; the termination signaling can also be directly sent to the base station through the bottom layer signal, the base station immediately stops the current symbol turn-off mode, and the base station informs the decision to the network side through the high layer signaling.
For example, after knowing that the current symbol turn-off is turned off, the network side can determine whether to reselect the current symbol turn-off mode as the network side to pre-configure the symbol turn-off mode according to the network measurement condition, and repeat steps 320-360.
