Embodiment Construction

[0039] Embodiments of the present invention provide a resource control method, system, base station, and terminal in a carrier aggregation system.

[0040] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.

[0041] Those skilled in the art know that in an LTE system, that is, an LTE-A system, a physical downlink control channel (Physical Downlink Control Channel, PDCCH) is used to schedule carrier resources. For the design of PDCCH scheduling carrier resources in the carrier aggregation system, there are several solutions as follows:

[0042] Solution 1: Each carrier sends a PDCCH independently, and the PDCCH in each carrier only schedules physical resources in the same carrier in the specified carrier set.

[0043] The principle of the scheme can be as image 3 Exemp...

Abstract

The invention discloses a resource control method, system, base and terminal in carrier polymerization system. The embodiment of the resource control method in carrier polymerization system includes: the base designates a main carrier needing the terminal monitoring for a terminal under a non-business data transmission state in an LTE-A system; the base determines the carrier transmission configuration of the business data after receiving a business data transmission request and indicates the terminal to monitor resource control information on the configured transmission carrier; the base determines the transmission configuration of the main carrier after completing the business data transmission with the terminal, and indicates the terminal to monitor the resource control information on the configured main transmission carrier. The invention can be used to realize flexible control on resources in carrier polymerization system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource control method, system, base station and terminal in a carrier aggregation system. Background technique [0002] The carrier aggregation system is a system for aggregating (or connecting) multiple carrier resources. For example, in the developing Long Term Evolution Advanced (LTE-A) system, in order to support a wider system bandwidth than the LTE system, for example, to support a bandwidth of 100MHz, multiple LTE carriers (or component carriers) ) resources are connected and used. These carriers can be bound as the entire bandwidth of the system and allocated to one user or to multiple users. When given to a user, a higher peak rate can be provided. [0003] In LTE-A, specifically, multiple consecutive LTE carriers may be aggregated, such as figure 1 As shown, alternatively, multiple discontinuous LTE carriers may be aggregated, such as fi...
