example one
An embodiment of the present invention provides a data transmission method, as shown in fig. 1, including:
s101, a base station acquires the current signal receiving quality of terminal Equipment (User Equipment, UE for short); the Signal Receiving quality includes at least one of Reference Signal Receiving Power (RSRP) and Signal-to-NOISE RATIO (SNR).
S102, judging whether the signal receiving quality meets a first preset condition or not by the base station; wherein the first preset condition comprises at least one of RSRP being greater than or equal to a target RSRP and SNR being greater than or equal to a target SNR.
It should be noted that, in practical applications, the RSRP and SNR measurement values are affected by the current environment of the terminal device; therefore, floating values need to be added to the target RSRP and the SNR to ensure the accuracy of the base station in judging whether the signal receiving quality meets the first preset condition; and the target RSRP and the target SNR are theoretical values under the condition of no interference.
Optionally, as shown in fig. 2 and fig. 6, when the signal reception quality is RSRP, the determining, by the base station, whether the signal reception quality meets a first preset condition includes: the base station judges whether the RSRP is larger than or equal to the target RSRP.
In particular, in practical applications when the RSRP _ UE is usedi≥RSRP_DiWhen the signal quality is higher than the preset value, + Δ RSRP, it is indicated that the signal quality at the current position of the terminal device is better, and the service data of the terminal device can be transmitted by adopting double HARQ; when RSRP _ UEi＜RSRP_DiWhen the signal quality at the current position of the terminal equipment is poor when the signal quality is + delta RSRP, the transmission quantity gain of the service data is not obvious when the service data of the terminal equipment is transmitted by double HARQ; therefore, the service data of the terminal equipment does not need to be transmitted by adopting double HARQ, and the service data of the terminal equipment can be transmitted by adopting single HARQ; wherein, RSRP _ UEiRSRP, RSRP _ D representing the ith UE measurementiIndicating the target RSRP at the location of the ith UE, and Δ RSRP indicating the float value.
Optionally, when the signal reception quality is SNR as shown in fig. 3 and fig. 6, the determining, by the base station, whether the signal reception quality meets a first preset condition includes: the base station determines whether the SNR is greater than or equal to the target SNR.
Specifically, in practical applications when SNR _ UEi≥SNR_DiWhen the signal quality is higher than the Δ SNR, the signal quality at the current position of the terminal device is better, and the service data of the terminal device can be transmitted by adopting a rate enhancement function; when SNR _ UEi＜SNR_DiWhen the signal quality at the current position of the terminal equipment is poor when the signal quality is + delta SNR, and when the service data of the terminal equipment is transmitted by adopting double HARQ, the transmission quantity gain of the service data is not obvious; therefore, the service data of the terminal equipment does not need to be transmitted by adopting double HARQ, and the service data of the terminal equipment can be transmitted by adopting single HARQ; wherein SNR _ UEiRepresents the SNR, SNR _ D, of the ith UE measurementiIndicates the target SNR at the location of the ith UE, and Δ SNR indicates the float value.
Optionally, as shown in fig. 4 and fig. 6, when the signal reception quality is RSRP and SNR, the determining, by the base station, whether the signal reception quality meets a first preset condition includes: the base station discriminates whether the RSRP is greater than or equal to a target RSRP and the SNR is greater than or equal to a target SNR.
In particular, in practical applications when the RSRP _ UE is usedi≥RSRP_Di+ Δ RSRP, and SNR _ UEi≥SNR_DiWhen the signal quality is higher than the Δ SNR, the signal quality at the current position of the terminal device is better, and the service data of the terminal device can be transmitted by adopting a rate enhancement function; when RSRP _ UEi≥RSRP_Di+ Δ RSRP, and SNR _ UEiLess than SNR _ Di+ Δ SNR, or RSRP _ UEi＜RSRP_Di+ Δ RSRP, and SNR _ UEi≥SNR_Di+ Δ SNR, or RSRP _ UEi＜RSRP_Di+ Δ RSRP, and SNR _ UEi＜SNR_DiWhen the signal quality at the current position of the terminal equipment is poor when the signal quality is + delta SNR, and when the service data of the terminal equipment is transmitted by adopting double HARQ, the transmission quantity gain of the service data is not obvious; therefore, the service data of the terminal equipment does not need to be transmitted by adopting double HARQ, and the service data of the terminal equipment can be transmitted by adopting single HARQ.
S103, determining that the signal receiving quality meets a first preset condition, and transmitting service data of the terminal equipment by adopting a rate enhancement function; wherein the rate enhancement function comprises at least HARQ.
Optionally, before transmitting the service data of the terminal device by using the rate enhancement function as shown in fig. 5 and fig. 6, the method further includes: the base station judges whether the current operation parameters meet a second preset condition or not; the current operation parameters comprise at least one of the number of users currently initiating an access request and the number of users waiting to be scheduled, the second preset condition comprises that the number of users currently initiating the access request is less than the channel capacity, and the number of users waiting to be scheduled is less than at least one of the number of system subcarriers; and if the signal receiving quality meets the first preset condition and the current operation parameter meets the second preset condition, transmitting the service data of the terminal equipment by adopting a rate enhancement function.
Optionally, when the current operation parameter is the number of users currently initiating the access request, the base station determines whether the current operation parameter meets a second preset condition, including: the base station judges whether the number of users initiating the access request is larger than or equal to the channel capacity or not.
Specifically, in practical application, when Num _ Access _ UE is less than Volim _ ch, it indicates that the number of users served by the base station is small and the number of remaining network resources is large; therefore, the service data of the terminal equipment can be transmitted by adopting the rate enhancement function; when Num _ Access _ UE is greater than or equal to Volim _ ch, it indicates that there are more users served by the base station at this time and there are fewer remaining network resources, and when the service data of the terminal equipment is transmitted by using dual HARQ, more network resources are occupied, which affects the Access of subsequent users; therefore, the service data of the terminal equipment needs to be transmitted by adopting a single HARQ, so that the access of other subsequent terminal equipment is ensured, and the user experience is ensured; the Num _ Access _ UE represents the total number of users initiating the Access request in the communication cell where the terminal device is located in unit time, and the Volim _ ch represents the upper limit of the channel capacity.
Specifically, in practical applications, the total number of bits actually transmitted by each channel is equal to the sum of the number of bits of the service data transmitted by each terminal device; therefore, the terminal equipment (i.e. the number of users) borne by each channel in the same time is fixed, and whether the number of users served by the current base station reaches the maximum number of users served by the current base station can be known by judging the capacity of the current channel, so that the service transmission rate of the users for accessing the users is ensured, and meanwhile, the access of subsequent users is ensured and the user experience is improved by controlling the service data adopting double HARQ transmission terminal equipment or adopting single HARQ transmission terminal equipment.
Optionally, when the current operation parameter is the number of users waiting for scheduling, the base station determines whether the current operation parameter meets a second preset condition, including: the base station judges whether the number of users waiting for scheduling is more than or equal to the number of system subcarriers.
Specifically, in practical application, when Num _ buffer _ UE is less than System _ ch, it indicates that the number of users served by the base station is small and the number of remaining network resources is large; therefore, the service data of the terminal equipment can be transmitted by adopting the rate enhancement function; when Num _ buffer _ UEiWhen the System _ ch is greater than or equal to the System _ ch, the base station services more users and the remaining network resources are less, and when the service data of the terminal equipment is transmitted by adopting double HARQ, more network resources are occupied, and the access of the subsequent users is influenced; therefore, the service data of the terminal equipment needs to be transmitted by adopting a single HARQ, so that the access of other subsequent terminal equipment is ensured, and the user experience is ensured; wherein Num _ buffer _ UE represents the number of users waiting to be scheduled in buffer at the ith moment, and System _ ch represents the number of System subcarriers; wherein each subcarrier carries service data of one user.
It should be noted that the size of a specified resource block (also called a transport block) in Long Term Evolution (Long Term Evolution, LTE for short) is 180 KHz; therefore, when the subcarrier interval of the base station on is 15KHz, the corresponding subcarrier number is 12(180/15 ═ 12); if the subcarrier interval of the base station is 3.75KHz, the corresponding subcarrier number is 48(180/3.75 equals 48).
For example, assuming that the subcarrier interval of the current base station is 15KHz, and the total number of users initiating access requests in the communication cell where the terminal device is located in a unit time is 20, the number of users waiting to be scheduled in the buffer at the ith time is equal to 8 (8-20-180/15).
Optionally, when the current operation parameter is the number of users currently initiating the access request and the number of users waiting for scheduling, the base station determines whether the current operation parameter meets a second preset condition, including: the base station judges whether the number of users initiating the access request at present is larger than or equal to the channel capacity or not, and whether the number of users waiting for scheduling is larger than or equal to the number of system subcarriers or not.
Specifically, in practical application, when Num _ Access _ UE is less than Volim _ ch and Num _ buffer _ UE is less than System _ ch, it indicates that the base station serves fewer users and the remaining network resources are more; therefore, the service data of the terminal equipment can be transmitted by adopting the rate enhancement function; when Num _ Access _ UE < Volim _ ch, and Num _ buffer _ UEiMore than or equal to System _ ch, or Num _ Access _ UE more than or equal to Volim _ ch, and Num _ buffer _ UEi< System _ ch, or Num _ Access _ UE ≧ Volim _ ch, and Num _ buffer _ UEiWhen the System _ ch is greater than or equal to the System _ ch, the base station services more users and the remaining network resources are less, and when the service data of the terminal equipment is transmitted by adopting double HARQ, more network resources are occupied, and the access of the subsequent users is influenced; therefore, the service data of the terminal device needs to be transmitted by using a single HARQ, so as to ensure the access of other subsequent terminal devices and ensure the user experience.
Specifically, volume _ ch is System _ ch × (1+ β); wherein beta represents a channel capacity proportionality coefficient, and beta is more than or equal to 0 and less than or equal to 1.
According to the scheme, the base station judges whether the service data of the terminal equipment is transmitted by adopting the rate enhancement function according to the current signal receiving quality of the terminal equipment, so that the problems that the transmission rate gain of the service data of the terminal equipment is not obvious and more resources are occupied because the base station still adopts the rate enhancement function to transmit the service data of the terminal equipment when the signal receiving quality of the terminal equipment is poor are solved.
