Problems solved by technology

[0010] In a typical FDD spectrum aggregation method, spectrum fragments cannot be deployed reasonably for the time being
For example, an FDD operator owns a pair of 20MHz symmetrical spectrum, in addition to an additional 10MHz frequency band; if the traditional LTE-Advanced system aggregates FDD spectrum, this frequency band can only be aggregated to the downlink or to the uplink. , the use of spectrum fragments lacks flexibility and effectiveness
Moreover, since users have different service requirements in different time periods, the uplink and downlink carriers in the system are fixedly configured using the existing technology. In order to ensure that the system can meet user needs in each time period, it is necessary to Configure the number of uplink and downlink carriers separately for the peak value, which will cause a waste of resources in the system

Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0030] The carrier aggregation system according to the embodiment of the present invention includes: uplink and downlink carriers appearing in pairs and independent carriers, some of the uplink and downlink carriers appearing in pairs are fixedly used to transmit downlink services, and the rest of the carriers are fixedly used to transmit uplink services , the independent carrier is aggregated with the uplink and downlink carriers that appear in pairs respectively in a TDM manner.

[0031] Compared with the FDD aggregation system in the typical FDD spectrum aggregation mode in the prior art, the carrier aggregation system in the embodiment of the present invention may be called an atypical FDD aggregation system....

Abstract

The invention discloses a frequency spectrum fragment processing method and equipment of a carrier polymerizing system. The method comprises the following steps: in an FDD polymerizing system, respectively polymerizing independent carriers with coupled up and down carriers in a manner of TDM, wherein the independent carriers are non up and down coupled carriers; when a user enters a cell for the first time, notifying the user the configuration information of the up and down carriers in the FDD polymerizing system by system information in broadcast messages, wherein the configuration information comprises the information of the independent carriers. By using the invention, relatively independent frequency spectrum fragments can be effectively utilized to be flexibly applied to asymmetrical services.

Description

technical field [0001] The present invention relates to communication technology, in particular to a carrier aggregation system and a spectrum fragment processing method and equipment thereof. Background technique [0002] At present, with the development of mobile communication technology, the system capacity is increasing exponentially. Therefore, high-speed services under high mobility are required to meet the continuously increasing user needs. Compared with voice services, multimedia services grow faster and gradually become the main service. need. Enhanced services and applications require higher peak rates. In order to increase the peak rate and the average throughput of each cell, wider bandwidth is required. [0003] In order to support a wider system bandwidth than the LTE (Long Term Evolution, long-term evolution) system, such as 100MHz, the LTE-Advanced system aggregates the resources of multiple LTE carriers (also called component carriers). At this stage, the...
