Semi-static resource scheduling method

Abstract

The invention discloses a semi-static resource scheduling method, which comprises the following steps of: in each initial transmission of semi-static transmission, counting the number of continuous correct packets and the number of continuous wrong packets of the initial transmission; and if the number of the continuous correct packets is greater than a set first threshold or the number of the continuous error packets is greater than a set second threshold, re-allocating semi-static resources according to the current channel quality. By applying the method, resource distribution can be reasonably carried out, and the system transmission performance is improved.

Description

technical field [0001] The present application relates to communication technology, in particular to a semi-static resource scheduling method. Background technique [0002] In the existing LTE standard, the base station generally realizes the scheduling processing of the voice data by means of semi-persistent scheduling. When the semi-persistent scheduling is successfully activated, a fixed frequency domain resource (RB resource) will be allocated for the voice data to be transmitted. During the entire voice service process, this fixed frequency domain resource is used for subsequent scheduling. In terms of time resources, it is scheduled once every semi-static scheduling period comes. [0003] In practical applications, since the terminal is mobile, for the terminal, the channel quality between the terminal and the base station changes. As the terminal moves, the channel quality may improve or deteriorate. For the terminal in the call, the following problems will occur: ...

AI Technical Summary

Problems solved by technology

[0004] 1. When the channel quality improves, if you continue to use the initially allocated fixed frequency domain resources to transmit voice data, there will be a certain waste of RB resources;

[0005] 2. When the channel quality deteriorates, the initial transmission error of semi-persistent scheduling will increase. If you continue to use the frequency domain resources originally allocated to this terminal to transmit voice data, the semi-persistent scheduling performance of this terminal will decrease.
