Carrier channel configuration method in multiple carrier communication system

Abstract

This invention discloses a configuration method for carrier channels in a multi-carrier communication system, which designs a TCA information format carrying with carrier channel configuration information to configure the MAC channels of zero or multiple reverse carriers to the forward carrier of the terminal, in which, the MAC channels can include DRC-Lock sub-channels or not and the corresponding relation between the channels or sub-channels and the carriers and the action time sequence are described in the TCA information, besides, the MAC channels of multiple reverse carriers can be configured on a same forward carrier to fully utilize the channel resources.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a carrier channel configuration method in a multi-carrier mobile communication system. Background technique [0002] With the increasing popularity of mobile communication, mobile voice communication alone can no longer meet the needs of people to obtain information. Mobile data communication services have shown great vitality and development because they can provide office, entertainment, and communication with others across geographical boundaries. prospect. As of August 2005, the number of China Mobile users has exceeded 370 million, and the mobile data service is developing rapidly, which is the key to a new growth point of mobile communication and to maintain its vigorous vitality. Code Division Multiple Access 2000 1x (Code Division Multiple Access 2000 1x, referred to as "CDMA2000 1x"), one of the third generation (3G) mobile communication technologies, Evolution Data Op...

Problems solved by technology

[0015] In practical applications, the above scheme has the following problems: each forward carrier can only support one MAC channel corresponding to a reverse carrier that transmits DRC and multiple MAC channels corresponding to multiple reverse carriers that do not transmit DRC, so it is only applicable to When the number of forward carriers is less than that of reverse carriers, it does not support the flexible allocation of reverse carriers and forward carriers carrying their corresponding forward MAC channels (including RPC, ARQ and DRC_Lock channels). The application scenarios are very limited, and the system Not flexible enough

Especially for some special application situations, such as the reverse and forward transmission volumes are very different, and the business changes quickly, it cannot meet the business needs well, and it cannot save the terminal transmit power and other resources to the greatest extent.

[0016] The main reason for this situation is that in the original scheme, only idle forward carriers can be established for redundant reverse carriers, which wastes power; although the solution proposed by LGE solves the problem of redundant direction carriers, for a forward carrier It is limited to support only one reverse carrier that transmits DRC, which restricts the flexibility of carrier channel configuration and limits the scope of application
