Fig. 2 is a schematic flow chart of a method 200 for controlling a power amplifier according to an embodiment of the present application. It should be understood that fig. 2 shows steps or operations of the method, but these steps or operations are only examples, and other operations or variations of the operations in fig. 2 may be performed by the embodiments of the present application, or not all the steps need to be performed, or the steps may be performed in other orders. The method 200 for controlling the power amplifier in fig. 2 includes:

s210, the BBU determines first indication information, and the first indication information is used for indicating a target code chip or a target symbol of the RU for turning off the power amplifier.

Wherein the BBU in method 200 of fig. 2 can be BBU121 in communication system 100 of fig. 1.

In the embodiment of the present application, source-coded data containing information may be referred to as bits (bits), channel-coded and interleaved data is referred to as symbols (symbols), and data obtained through final spreading is referred to as chips (chips).

In the spreading, the original narrow-band signal is changed from Spreading Factor (SF) to a wide-band signal, and then the original signal is despread by the same spreading factor at the receiving end. The signal spectrum after spread spectrum has wide bandwidth, strong anti-interference capability and good confidentiality, and can also bring higher spread spectrum gain.

In WCDMA systems, the spreading factor is the sequence number of the spreading code, indicating how many bit chips (chips) are used to represent an information symbol (bit), and may take the value of n times 2, for example,

SF

2, 4, 8 … 512, where n is a positive integer. Commonly used spreading codes are Orthogonal Variable Spreading Factor (OVSF) codes, etc., and the number of chips into which each symbol is converted is called a spreading factor.

For example, in a WCDMA system, OVSF codes can be used to spread information symbols and spread symbol sequences into chip sequences, thereby ensuring orthogonality between traffic channels of different users or different traffic channels of the same user.

In this embodiment of the present application, the BBU may identify a target chip or a target symbol that the power amplifier can be turned off, or the BBU may identify a target chip or a target symbol that the power amplifier needs to be turned on, so as to determine first indication information, where the first indication information may be used to indicate the RU to turn off the target chip or the target symbol of the power amplifier.

It should be understood that the first indication information may be used to indicate a target chip or a target symbol that the RU can turn off, or the first indication information may also be used to indicate a target chip or a target symbol that the RU needs to turn on.

In this embodiment of the present application, the BBU may determine the first indication information according to service data carried in chips or symbols.

That is to say, the BBU may determine, according to service data carried in a chip or a symbol, a target chip or a target symbol to which the power amplifier can be turned off, and further determine the first indication information. Or, the BBU may also determine a target chip or a target symbol on which the power amplifier needs to be turned on according to service data carried in the chip or the symbol, and further determine the first indication information.

In the embodiment of the present application, the first indication information may be used to indicate a target chip or a target symbol. That is, the first indication information may directly indicate the target chip or the target symbol.

For example, the BBU or the RU may agree or configure in advance that the first indication information indicates a target chip or a target symbol that the RU can turn off, and after receiving the first indication information sent by the BBU, the RU may directly turn off the target chip or the target symbol of the power amplifier.

For another example, the BBU or the RU may agree or configure in advance that the first indication information indicates a target chip or a target symbol that the RU needs to turn on, and after receiving the first indication information sent by the BBU, the RU may directly turn off chips or symbols other than the target chip or the target symbol that needs to turn on.

Optionally, the first indication information is used to indicate a starting time of the target chip or the target symbol and/or a duration of the target chip or the target symbol.

Optionally, the first indication information may be used to indicate a time period in which the power amplifier can be turned off. It should be understood that the time period capable of turning off the power amplifier may refer to a time period in which the target chip or the target symbol of the power amplifier is capable of being turned off. Or, the first indication information may be used to indicate a time period in which the power amplifier needs to be turned on.

Optionally, the time period for turning off or turning on the power amplifier, which is indicated by the first indication information, may be a plurality of time periods which are discontinuous in a time domain.

In this embodiment of the present application, when the transmission power of the RU is smaller than a preset value, the BBU may determine the first indication information.

It should be understood that the BBU and the RU may constitute a network device, and that a transmit power of the RU being less than a preset value may mean that a power load of the network device is less than a preset value. For example, that the transmission power of the RU is less than a preset value may mean that the power load of the network device is low.

According to the method provided by the embodiment of the application, the RU can be ensured to turn off the power amplifier when the network load is low, and the power amplifier is prevented from turning off to cause large negative effects on network services and user experience.

S220, the BBU sends the first indication information. Accordingly, the RU receives the first indication information.

Wherein the RU in method 200 of fig. 2 may be RU 122 in communication system 100 of fig. 1.

In this embodiment of the present application, the BBU may carry the first indication information in data sent to the RU.

Optionally, the BBU may add predefined sequence information to the data to indicate the first indication information.

And S230, the RU turns off the power amplifier at the target chip or the target symbol according to the first indication information.

In the embodiment of the present application, the target chip or the target symbol may not carry traffic data.

For example, the first indication information may be used to indicate a symbol that does not carry traffic data. For example, the first indication information may be used to indicate symbols such as pilot symbols that do not carry traffic data, symbols in a channel that do not carry traffic data, or symbols that do not affect traffic data in a channel.

For another example, the first indication information may be used to indicate a target symbol that needs to carry traffic data. At this time, after receiving the first indication information, the RU may directly turn off symbols other than the target symbol that needs to carry the service data

In the embodiment of the present application, the target chip or the target symbol may be pre-configured.

For example, the target chip or the target symbol may be a pre-configured pattern (pattern), and the RU turns off the power amplifier according to the pre-configured pattern.

In a possible implementation manner of the embodiment of the present application, the pre-configured pattern may be stored in the BBU, and when the BBU determines that the power amplifier needs to be turned off, the first indication information is determined, and the first indication information is sent to the RU. Optionally, the first indication information may include the preconfigured pattern.

In another possible implementation manner of the embodiment of the present application, the pre-configured pattern may be stored in the RU, and when the BBU determines that the power amplifier needs to be turned off, the first indication information is sent to the RU. Correspondingly, after receiving the first indication information, the RU turns off the target chip or the target symbol according to the pre-configured pattern stored by the RU. It can be seen that, at this time, the first indication information corresponds to switching information for indicating to turn off a target chip or a target symbol.

In the embodiment of the present application, the RU may increase the transmission power of the time slot in which the power amplifier is not turned off.

According to the method of the embodiment of the application, the RU increases the transmitting power in the time slot without turning off the power amplifier, can compensate the spread spectrum gain loss and the symbol energy weakening caused by turning off the target chip or the target symbol, and avoids the reduction of the signal-to-noise ratio of the symbol.

In the embodiment of the present application, the RU may be turned off by a symbol, for example, the symbol may include 256 chips. For the pilot and most downlink common channels, the length of the downlink symbol is 256 chips, so the RU can be turned off by 256 chips.

Optionally, the BBU may identify a target symbol that does not carry service data in the traffic channel, or the BBU may identify a target symbol that does not affect service data in the traffic channel, determine first indication information according to the target symbol, and send the first indication information to the RU. Accordingly, the RU may receive the first indication information, and turn off the power amplifier at the target symbol according to the first indication information.

Optionally, the BBU may carry the first indication information in data sent to the RU. For example, the BBU may add an all-zero bit in the target symbol that needs to be turned off to indicate that the target symbol needs to be turned off. For example, the BBU may add "0000" to the target symbol that needs to be turned off to indicate that the target symbol needs to be turned off.

Correspondingly, after the RU receives the target symbol, if it is determined that the target symbol includes a full zero bit, the power amplifier is turned off at the target symbol.

After turning off the symbols, the snr of these channels may decrease, and at this point, the RU may increase the snr of the symbols that have not been turned off to avoid the snr of the channels from decreasing.

In this embodiment of the present application, after turning off the symbol, the RU may turn on the power amplifier at a fixed time. For example, if the length of the power amplifier is turned off is 16 chips, the RU may automatically turn on the power amplifier after executing 16 chips after the power amplifier is turned off; the length of the power amplifier is 256 chips, and the RU can automatically start the power amplifier after executing 256 chips after the power amplifier is turned off. After the starting, the radio frequency module will continue to detect the next first indication information, so as to turn off the power amplifier at the target code sheet or the target symbol.

The following describes an embodiment of turn-off by chip with reference to fig. 3, taking an example of turning off in a period of 4 chips for one symbol with Spreading Factor (SF) of 16. In fig. 3, black boxes transmit the used chips for RUs.

As shown at S310 in fig. 3, the RU performs normal spreading and transmits continuously by 16 chips with a transmission power of 2 watts (w).

In S320, the RU turns off the chips in a period of 4 chips. At this time, in the case where the transmission power is not changed, since half of the chips are turned off, the symbol loses 50% of the chip energy and 50% of the spreading gain, and thus the symbol energy is only 1/4 in the normal transmission in S310.

In S330, the transmission power of the time slot of the non-turned-off power amplifier is increased to 8w in order to compensate for the loss of the symbol energy.

In the above embodiment, since the power amplifier is in the normal operating mode, the transmission power of the time slot in which the power amplifier is not turned off is increased, and the influence on the energy consumption is small. And under the time slot of the turn-off chip, the energy consumption of the power amplifier is reduced to be nearly zero, so that the embodiment can save the energy consumption of the power amplifier by 50 percent, but does not bring the loss of symbol energy.
