Embodiment Construction

[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] The present application provides a method based on multi-carrier aggregation scheduling, which determines whether to activate the secondary cell by considering the amount of MAC layer data of the primary cell for the terminal and the total load of the secondary cell corresponding to the configured secondary carrier.

[0015] After a terminal is connected, the base station compares the reference signal receiving power (Reference Signal Receiving Power, RSRP) of the carrier measured and reported by the terminal with the locally configured RSRP of the corresponding carrier, and compares the N carriers that meet the measurement threshold. , is added as a secondary carrier through the reconfiguration message, that is, carrier...

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...
