Description

The transmission method of upstream data and device in carrier convergence

Technical field

The invention belongs to the communications field, relate in particular to transmission method and the device of upstream data in carrier convergence.

Background technology

Along with the development of mobile communication technology, transmission rate and service quality that system can provide are more and more higher, and customer service has also proposed more and more higher requirement to transmission rate, in order to guarantee general user's speed, simultaneously for a part of user provides higher throughput, in the situation that avoiding significantly increasing configured bandwidth, 3GPP(three generations partner program) introduce carrier aggregation (Carrier Aggregation, CA) technology, its scheme is mainly subscriber equipment (User Equipment, UE) can use multiple member carriers (Component Carrier simultaneously, CC) carry out uplink and downlink communication, thereby support high speed data transfer, and in the time that user rate reduces, can also discharge some member carriers, only retain a resident carrier wave, and the transfer resource discharging can be used for other users, thereby reach flexible, dynamic transmission object.

In station intercarrier converges, conventionally use two kinds of base stations: macro base station and little base station, macro base station mainly uses low-frequency range component carrier extensively to cover, in order to carry out well mobile management and to be connected control.And small base station mainly uses high band component carrier, its feature is mainly aboundresources, can distribute very large bandwidth for transfer of data, and the carrier wave of for example 3.5GHz or 6GHz, can provide high speed data transmission service for UE.Between the wide base station covering and the base station of little covering, generally use optical fiber, DSL(DigitalSubscriber Line digital subscriber line), the variety of way such as wireless connects, and intercoms mutually for the macro base station of wide covering and the little base station of little covering.In the time using optical fiber to carry out being directly connected of macro base station and little base station, propagation delay time between the two is approximately 0, and non-optical fiber is connected between macro base station and little base station, or while being indirectly connected by optical fiber, propagation delay time between the two generally be can not ignore, and generally speaking can be assumed to be 10-20ms.
