Abstract

The embodiment of the invention provides a discontinuous receiving method, a scheduling method and a scheduling device for carrier aggregation. The discontinuous receiving method for the carrier aggregation comprises the following steps of: acquiring information of the monitored downlink member carrier set and a main member carrier inside the downlink member carrier set; and switching between a first monitoring mode and a second mode according to a network trigger event in a discontinuously received activation state; only monitoring the scheduling information of the member carrier in the first monitoring mode; and monitoring the scheduling information of all the member carriers in the set in the second monitoring mode. The discontinuous receiving method balances the throughput and fulfills the aim of power conservation.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a carrier aggregation discontinuous reception method, scheduling method and device. Background technique [0002] Mobile communication technology has been developed to the third generation. In order to maintain a long-term competitive advantage, in the existing Global System for Mobile Communication (Global System For Mobile Communication, GSM), Global Terrestrial Radio Access (Universal Terrestrial Radio Access, UTRAN), High-speed Link Packet Access (High- On the basis of mature standards such as SpeedPacketAccess (HSPA), the 3GPP organization further develops long-term evolution (LTE) standard production. In order to support wider transmission bandwidth and improve system throughput, especially user throughput, carrier aggregation (carrier aggregation, CA) technology, carrier aggregation means that one or more component carriers are aggregated together to become ...
