Abstract

The invention provides a scheduling method based on multi-carrier aggregation, and the method comprises the steps: enabling a base station to configure N-carrier aggregation for any one terminal; traversing a configured auxiliary cell in any one activation period according to a configured auxiliary carrier sequence when a main cell is activated for the terminal and the data size of the MAC layer of the main cell is greater than an activation threshold value; activating the data size of the MAC layer of the auxiliary cell when the auxiliary cell with the total load being not greater than a load threshold value and the terminal is in a non-activated state, and distributing the data size of the MAC layer of the main cell of the terminal to the main cell and the auxiliary cell according to a preset rule. The method optimizes the multi-carrier aggregation scheduling, and reduces the consumption of resources.

Description

technical field

[0001] The present invention relates to the field of communication technologies, and in particular, to a method based on multi-carrier aggregation scheduling. Background technique

[0002] Due to frequency band and bandwidth limitations, multi-carrier aggregation has been more and more widely used in time division duplex (TDD) and frequency division duplex (FDD) systems, assuming the number of carrier aggregation is N, when N is 2, 2 These carriers are the primary carrier and the secondary carrier respectively; when N is greater than 2, there is one primary carrier and at least two secondary carriers, and the research on the scheduling method between multiple secondary carriers must be considered when multi-carrier aggregation.

[0003] To better manage the battery consumption of user terminals (UEs) configured with carrier aggregation, Long Term Evolution (LTE) provides an activation / deactivation mechanism for SCells. The existing carrier aggregation techno...
