Embodiment Construction

[0133] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0134] At first, introduce the theoretical basis that the present invention relates to:

[0135] According to prior art 2, for the minimum energy consumption transmission curve with arrival constraint and cut-off constraint, any transmission segment has the minimum slope when intersection A(t) is prior to intersection D(t) (obviously At this time, the intersection point with A(t) must be a data packet arrival point), or it has the largest slope when the intersection D(t) precedes the intersection A(t) (obviously, the intersection point with D(t) must be is a packet cut-off point). Given the start point of a transmission segment, if the end point corresponds to the first case, set Then, between the start point and the end point of the transmission se...

Abstract

The invention discloses a data packet transmission and scheduling method and a device based on interactive slope comparison, which belong to the field of wireless communication. The method comprises steps: starting from the beginning of a transmission section, arrival slopes of data packet arrival points are calculated according to a time sequence, cutoff slopes of data packet cutoff points are calculated, and the minimal arrival slope and the maximal cutoff slope rmax are updated; when detected to be smaller than or equal to the rmax, the former one of corresponding time in the rmax is the transmission rate of the transmission section, the arrival point or the cutoff point of the corresponding data packet is the beginning of a next transmission section; according to the above process, each transmission section and the transmission rate thereof are found out sequentially; and according to the obtained transmission sections and the transmission rates, data packet transmission is carried out. Compared with the prior art, the data packet transmission and scheduling method based on interactive slope comparison can realize the lowest energy consumption transmission.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a data packet transmission scheduling method and device based on interactive slope comparison. Background technique [0002] In the context of increasingly tight energy resources, the pursuit of higher energy efficiency is an important goal of wireless communication development, and low-energy data packet transmission is a key part of achieving higher energy efficiency in future wireless communication. For a data packet of a given size, the smaller the transmission rate and the longer the transmission time, the smaller the corresponding transmission energy consumption. In the following, an AWGN (Additive White Gaussian Noise, Gaussian white noise) transmission channel will be taken as an example, and the above conclusions will be described in combination with Shannon's theorem. [0003] In a given channel bandwidth B and noise power spectral density N 0 In the case of , Sh...
