Problems solved by technology

[0010] From the above analysis, we can see that for a radio terminal with only a single link, power consumption and communication interruption are the two most critical problems, and neither the explicit command method nor the implicit command method can solve the above problems at the same time

Abstract

The invention relates to a communication method of secondary cells of activated terminals and deactivated terminals and an electronic device. The electronic device comprises a processing circuit, wherein the processing circuit is used for configuring a plurality of secondary cells for gathering carriers and activating or deactivating at least one of the secondary cells based on combination of an implicit manner and an explicit manner. The processing circuit is also used for activating or deactivating at least one of the secondary cells according to a control signaling of an activated or deactivated media access control layer; the control signaling of the activated or deactivated media access control layer comprises a plurality of bits used for indicating activated or deactivated states of the secondary cells by using specific cell indexes.

Description

[0001] This application is a divisional application of a patent application with an application date of August 13, 2010, an application number of 201010254678.4, and an invention title of "Method and device for activating and deactivating the uplink of a secondary cell of a terminal". technical field [0002] The present application relates to the communication field, and in particular to a method and device for activating and deactivating an uplink of a secondary cell of a terminal (User Equipment). Background technique [0003] The future LTE-A (Long Term Evolution Advanced) system will support a transmission bandwidth of up to 100MHz, while the maximum transmission bandwidth supported by the LTE (Long Term Evolution) standard is 20MHz, so multiple carriers need to be aggregated to achieve higher transmission bandwidth. Carrier Aggregation (Carrier Aggregation) is a technology proposed by 3GPP (3rd Generation Partnership Project) to support the higher transmission bandwidt...
