In addition, the channel shutdown is to shut off part of the radio frequency channels of the base station when the service load of the base station is low, and the channel shutdown characteristic is not effective when no trigger condition with low service load exists, so that the service data of the UE is transmitted through all the radio frequency channels all the time, thereby causing unnecessary channel power waste and increasing the energy consumption of the base station.

In order to reduce the energy consumption of the base station, an energy-saving method based on the base station turn-off characteristics such as symbol turn-off and channel turn-off is provided, and the basic principle is to turn off part of hardware resources of the base station when the network is idle, so that the energy-saving effect is achieved. First, the present application provides a network configuration, which is shown in fig. 1 and includes a base station and UEs 1 to UE n, where the UEs 1 to UE n establish communication connection with the base station as users of the base station.

The present application further provides a method for symbol blanking of a base station, specifically referring to fig. 3, wherein n symbol times are provided on a time axis of an Orthogonal Frequency Division Multiplexing (OFDM) symbol, at a certain time, the base station receives the service data transmission request of the user terminal, and randomly allocates the service data to the 3 rd to 6 th, 8 th to 13 th and 18 th symbol times for transmission, all radio frequency channels are in open state, no service data exists in 1-2, 7, 14-17 symbol time, then the radio frequency channel of the base station can be closed, therefore, the service initiation opportunity of the user terminal has randomness, so that service data is randomly and dispersedly distributed in each symbol time, the number of symbols without service data transmission is limited, the time proportion of the symbol turn-off characteristic in effect is small, and the energy-saving effect is not obvious.
In view of the foregoing problems, an embodiment of the present application provides a method for transmitting service data, which is shown in fig. 4 and specifically includes the following steps:
401. and acquiring a target service data transmission request.
The target service data transmission request comprises a target service type of a target service and a signal quality parameter of the target service; the target service type comprises a first type service and a second type service.
Specifically, the first type of service is a low-latency type of service, that is, a delay-sensitive service with a high requirement on latency of service data transmission, for example, a voice service, a high-reliability low-latency communications (urrllc) service, and the like. The second type of service is a high latency type of service, that is, a non-latency sensitive service with a low latency requirement on service data transmission, for example, services such as enhanced mobile broadband (eMBB) and large-scale internet of things (mip) applications.
The signal quality parameter of the target service reflects the strength of a downlink signal transmitted by the base station and received by the UE, for example, the Reference Signal Receiving Power (RSRP), and the larger the RSRP value is, the better the quality of the downlink signal transmitted by the base station and received by the UE is, wherein the RSRP of the base station is periodically measured after the UE accesses the base station, and the RSRP of the base station is reported to the base station through the target service data transmission request.
Further, the target service data transmission request further includes information such as a UE identifier, a base station identifier, and the like, for identifying the base station and the UE.
402. And determining the transmission time of the target service data according to the target service type.
If the target service is the first type service, determining the starting time of the next symbol time for receiving the target service data transmission request as the transmission time of the target service data; for example, referring to FIG. 5, on the time axis of the OFDM symbol, S x Receiving a target service data transmission request of the first type service at each symbol time, and sending the S-th service x+1 The initial time of each symbol time is used as the transmission time of the target service data.
And if the target service is a second type service, acquiring a service data transmission request received in a preset time period, wherein the initial time of the preset time period is the starting time of the next symbol time for receiving the target service data transmission request, the last time of the preset time period is the starting time of the (m + 1) th symbol time after m symbol times from the initial time, and m is more than or equal to 1. And determining the transmission time of the target service data according to the service type in the service data transmission request received in the preset time period.
Specifically, if a service data transmission request of a first type service is received at a first time within a predetermined time periodAnd if so, determining that the starting time of the next symbol time of the symbol time at which the first moment is located is the transmission time of the target service data, wherein the first moment is any moment in a preset time period, and starting to transmit all the received service data of the second type service, the target service data and the service data of the first type service in the time period before the transmission time of the target service data in the preset time period at the transmission time of the target service data. For example, referring to fig. 6, on the time axis of the OFDM symbol, the predetermined period is T 0 ～T d At T 0 Time of day (T) 0 The moment of time being a predetermined time period T 0 ～T d The start time of the next symbol time at which the target service data transmission request is received) is received within a symbol time preceding the symbol time at which the target service data transmission request is received, T 0 A service data transmission request of a second type service is received at the moment T 1 A service data transmission request of a second type service is received at the moment T 2 The T can be determined by receiving the service data transmission request of the first type service at any moment 2 The time is a first time, wherein T 0 <T 1 <T 2 <T d Due to T 2 The moment is both S 1 Last moment of symbol time, also S 2 An initial moment of the symbol time, at which T of the service data transmission request of the first type service is determined 2 At the time S 1 Determining the transmission time of the target service data as S at the last moment of the symbol time 2 Initial time of symbol time, and target service data, T 0 Receiving service data and T of the second type service at any moment 1 Receiving service data and T of the second type service at any moment 2 The service data of the first type service is received at the moment and is all in the transmission time of the target service data, namely S 2 The initial instant of the symbol time starts to transmit.
Specifically, if the service data transmission request of the first type service is not received within the predetermined time period, the number of times of receiving the service data transmission request of the second type service within the predetermined time period is obtained.
Further, if it is determined that the number of times of receiving the service data transmission request of the second type service in the time period from the initial time of the predetermined time period to the second time is greater than the first threshold, the starting time of the next symbol time of the symbol time where the second time is located is taken as the transmission time of the target service data, wherein the second time is any time in the predetermined time period, and in the time period before the transmission time of the target service data in the predetermined time period, all the received service data of the second type service and the target service data start to be transmitted at the transmission time of the target service data. For example, referring to fig. 7, on the time axis of the OFDM symbol, the predetermined period is T 0 ～T d The first threshold is preset to 3 at T 0 Time of day (T) 0 The moment of time being a predetermined time period T 0 ～T d The start time of the next symbol time at which the target service data transmission request is received) is received within a symbol time preceding the symbol time at which the target service data transmission request is received, T 0 、T 1 、T 2 、T 3 The service data transmission request of the second type service is received at the moment T 0 To T 3 The number of times of receiving the service data transmission request of the second type service is 4 at any moment, and the T can be determined when the number of times is larger than the first threshold value 3 The time is the second time, wherein T 0 <T 1 <T 2 <T 3 <T d Due to T 3 The moment is not only S 2 Last moment of symbol time, also S 3 Initial time of symbol time, at which T of service data transmission request of the fourth second type service is determined 2 At a time S 2 Determining the transmission time of the target service data as S at the last moment of the symbol time 3 Initial time of symbol time, and target service data, T 0 To T 3 The transmission time of the service data of the second type service received at the moment in the target service data is S 3 The initial instant of the symbol time starts to transmit.
Further, if the number of times of receiving the service data transmission request of the second type service in the preset time period is determined to be less than or equal to the first threshold, the last time of the preset time period is taken as the transmission time of the target service data, and the target service data is transmitted at the last time of the preset time period; and transmitting the service data of other second type services received in the preset time period at other time after the last time of the preset time period. For example, referring to fig. 8, on the time axis of the OFDM symbol, the predetermined period is T 0 ～T d The first threshold is preset to 3 at T 0 Time of day (T) 0 The moment of time being a predetermined time period T 0 -T d The initial time of the next symbol time at which the target service data transmission request is received) is received within a symbol time preceding the next symbol time at which the target service data transmission request is received 0 Receiving service data transmission request of two types of service at time T 1 Time of day (predetermined time period T) 0 ～T d At any one time) receives a service data transmission request of the second type service, and then reaches T d No more service data transmission requests are received at that moment, it can be obtained at T 0 To T d The number of times of receiving the service data transmission request of the second type service is 2, if the number is less than the first threshold value, the T is sent d Determining the time as the transmission time of the target service data, and setting the target service data at T d Starting transmission at the moment, and receiving service data of other second type services within a preset time period at T d The other time instants after the time instant are transmitted. For another example, referring to fig. 9, the predetermined period is T on the time axis of the OFDM symbol 0 ～T d The first threshold is preset to 3 at T 0 Receiving a target service data transmission request at the moment, and then sending to T d No more service data transmission requests are received at that moment, can be obtained, at T 0 To T d The number of times of receiving the service data transmission requests of other second type services is 0, if the number of times is less than the first threshold value, the T is set d The time is determined as the transmission time of the target service data, andtarget service data is in T d The transmission is started at that moment.
The first threshold is preconfigured, for example, the first threshold may be a default value, pre-stored, or obtained by being rewritten by a back-office manager, and for example, the first threshold is preconfigured for 3 times. The predetermined time period is also preconfigured, e.g. preconfigured to T 0 ～T d Then T is d Is from T 0 Symbol time S after m symbol times have elapsed d The starting time of (a); t is d And T 0 The time delay between is equal to the total duration of m symbol times, i.e. T delay ＝m×S Tsymbol Wherein, T delay Representing the total duration of m symbol times, m representing the symbol time S d And S 0 The number of the symbols between the first type of service and the second type of service is equal to or greater than 1, and the larger the value of m is set, the fewer the number of the symbols transmitted by the service data is, the more the number of the symbols which can be turned off is, but the larger the transmission delay of the service data of the second type of service is; s. the Tsymbol The duration of a single symbol time is a fixed value, and different values are adopted in the 4G system and the 5G system according to protocol convention respectively.
403. And determining a radio frequency channel required to be occupied by target service data transmission according to the signal quality parameter.
If the signal quality parameter is smaller than the second threshold, it is determined that all radio frequency channels need to be occupied for target service data transmission, for example, when the second threshold is preset to-110 dBm, the signal quality parameter of the target service is an RSRP value, and the RSRP is-120 dBm, it is determined that all radio frequency channels need to be occupied for target service data transmission because-120 dBm is less than-110 dBm.
If the signal quality parameter is greater than or equal to the second threshold value, then according to the formula
Calculating the number of radio frequency channels required to be occupied by target service data transmission, wherein N represents the number of radio frequency channels required to be occupied by target service data transmission, and N is more than or equal to 4 and less than or equal to N max ，N max Representing the maximum number of radio frequency channels supported by the base station, n representing a threshold for signal reference qualityValue grade, n is more than or equal to 1.
Specifically, the number of radio frequency channels that need to be occupied for target service data transmission is determined according to a signal quality parameter, the better the signal quality is, the smaller the number of radio frequency channels that are occupied is, and since the UE can generally support Active Antenna Unit (AAU) equipment of 2T4R at most, the base station equipment uses 4 radio frequency channels at least for data transmission, thereby forming downlink 4 × 4 multi-stream transmission and ensuring downlink data transmission performance, therefore, the number N of radio frequency channels that need to be occupied for target service data transmission is set to be 4 ≤ N max 。N max Indicating the maximum number of rf channels supported by the base station, and the value is related to the AUU device, e.g. for the AAU device of 64T64R, N max Value of 64, N for an AAU device of 32T32R max Value 32, for an AAU device of 16T16R, N max The value is 16. n represents a threshold level of signal reference quality, and its value is related to the AUU device, for example, for an AAU device of 64T64R, n may be 1, 2, 3, 4, for an AAU device of 32T32R, n may be 1, 2, 3, and for an AAU device of 16T16R, n may be 1, 2.
For example, taking AAU equipment of 64T64R as an example, the value of N is determined by the following method:
if the signal reference quality is greater than or equal to the second threshold and less than the fourth threshold, determining that the target service data transmission needs to occupy
And the radio frequency channel, n is 1, the first threshold level is taken, and the second threshold to the fourth threshold of the signal reference quality are corresponded.
If the signal reference quality is greater than or equal to the fourth threshold and less than the fifth threshold, determining that the target service data transmission needs to occupy
And the radio frequency channel, n is 2, the second threshold level is taken, and the fourth threshold to the fifth threshold correspond to the signal reference quality.
If the signal reference quality is greater than or equal to the fifth threshold and less than the sixth thresholdThreshold value, then determining that the target service data transmission needs to be occupied
And (3) taking a third threshold level corresponding to a fifth threshold to a sixth threshold of the signal reference quality.
If the signal reference quality is greater than or equal to the sixth threshold, determining that the target service data transmission needs to be occupied
And the radio frequency channel, n is 4, the fourth threshold level is taken, and the signal reference quality is more than or equal to the sixth threshold.
Further, the second threshold to the fifth threshold are preset reference signal quality thresholds, which can be set as empirical values according to operator requirements and satisfy: the second threshold < the fourth threshold < the fifth threshold < the sixth threshold, for example, the reference signal quality is an RSRP value, values of the second threshold, the fourth threshold, the fifth threshold, and the sixth threshold may be preset to-110 dBm, -100dBm, -90dBm, -80 dBm. For another example, when the signal quality parameter RSRP of the target service is-80 dBm, the available target service data transmission needs to occupy 4 radio frequency channels because-80 dBm is ≧ 80 dBm.
