Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with specific embodiments.

[0027] The present invention relates to carrier aggregation. Due to the complexity of component carriers in carrier aggregation, it is necessary to clearly indicate the component carriers, so that the advantages of carrier aggregation can be fully utilized to aggregate different carriers to form carriers with larger bandwidths. For this reason, the main idea of ​​the present invention is: set the component carrier indicator field in the base station (Base Station, BS) and determine the component carrier indicator field according to the user equipment resources, and the base station configures the component carrier for the UE according to the component carrier indicator field.

[0028] Since the base station performs corresponding instructions and configurations on the component carriers, it can ensure good application of the ...

Abstract

The invention provides a component carrier indication and collocation method and a component carrier indication and collocation device in carrier aggregation. The method comprises that: a base station sets a component carrier indication field and determines the component carrier indication field according to a user equipment resource; and the base station collocates component carrier for the user equipment resource according to the component carrier indication field. The device comprises a component carrier indicator and a component carrier collocation device at the base station, wherein the component carrier indicator is used for setting the component carrier indication field and determining the component carrier indication field according to the user equipment resource; and the component carrier collocation device is used for collocating the component carrier for the user equipment according to the component carrier indication field. The method and the device can clearly indicate how the user equipment uses the component carrier, ensure good application of the carrier aggregation technology, and reduce signaling interaction between the base station and the user equipment on the use of the component carrier so as to reduce system overhead.

Description

technical field [0001] The present invention relates to carrier aggregation technology, in particular to a method and device for indicating and configuring component carriers in carrier aggregation. Background technique [0002] In the next-generation broadband wireless communication network, how to support a larger bandwidth in the wireless communication network under the bandwidth of the current wireless communication system becomes a key factor in improving the throughput of user terminals between cells and the average throughput of user terminals. Facing severe challenges. [0003] The LTE-A system (Long Term Evolution-Advanced, Advanced Long Term Evolution) is a next-generation evolution system of the LTE (Long Term Evolution, Long Term Evolution) system of 3GPP (Third Generation Partnership Project), which proposes Carrier Aggregation (Carrier Aggregation) ) technology, in order to provide greater bandwidth for User Equipment (UE) and increase the peak rate of UE, so ...
