Embodiment Construction

[0064] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0065] In order to solve the problem in the prior art that the throughput of the UE cannot be maximized due to the limited UE power, in the embodiment of the present invention, the transmission parameters of the UE to be scheduled on each component carrier through carrier aggregation are respectively calculated, and according to the above The transmission parameters and preset determination rules determine aggregated carriers for uplink transmis...

Abstract

The present invention relates to the technical field of communications, and specifically relates to an uplink scheduling method and device for carrier aggregation. The method comprises: separately computing, for each component carrier after carrier aggregation, a transmission parameter of a UE unit to be scheduled, wherein the component carriers comprise PCells and SCells of the UE unit to be scheduled; determining, on the basis of the transmission parameter for each component carrier of the UE unit to be scheduled and according to a preset determination rule, a component carrier for uplink scheduling from the PCells and SCells of the UE unit to be scheduled; and allocating, on the basis of the component carrier for uplink scheduling, resources. In this way, the present invention enables flexible selection of a carrier involved in uplink scheduling for carrier aggregation from component carriers of a UE unit to be scheduled, thus preventing performance from being influenced by power reduction of the UE unit, maximizing the advantageous effects of carrier aggregation, and improving the throughput of the UE unit.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a carrier aggregation uplink scheduling method and device. Background technique [0002] In the Long Term Evolution (LTE) system, the serving cell is a cell that provides data transmission services for user equipment (UE), and each UE has at most one serving cell, but carrier aggregation is introduced in Rel-10 (Carrier Aggregation, CA) technology, the UE can have multiple serving cells at the same time, that is, the system aggregates two or more available carriers together to form a larger transmission bandwidth and achieve a higher transmission rate. Provide a better service experience. Therefore, the serving cell of the UE is divided into two categories: Primary Cell / Primary Component Carrier (PCell / PCC) and Secondary Cell / Secondary Component Carrier (SCell / SCC). ), wherein the PCell inherits the nature of the serving cell in the LTE system, and the SCell is o...
