Problems solved by technology

[0005] However, the current LTE-A system design does not consider the configuration of uplink and downlink on different carriers in TDD mode. There is no related solution, and it is impossible to ensure that R8 terminals work normally on each component carrier.

Embodiment Construction

[0040] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0041] figure 2 It is an overall flow chart of the uplink and downlink configuration method of TDD system carrier aggregation provided by the present invention. like figure 2 As shown, the method includes:

[0042] Step 201, independently perform uplink and downlink configuration for each component carrier participating in the aggregation in the cell, and ensure that there is at least one identical uplink subframe and at least one identical downlink subframe between at least two component carriers, and the configuration of at least one component carrier conforms to Uplink and downlink configuration of R8.

[0043] The present invention proposes that for an LTE-A TDD system, the uplink and downlink configurations on each component carrier can be configured indep...

Abstract

The invention provides an uplink-downlink configuration method of a TDD system carrier aggregation, comprising the following steps of: independently carrying out uplink-downlink configuration on all member carriers that participate in the aggregation in a cell, and ensuring that at least one same uplink subframe and at least one same downlink subframe exist between at least two member carriers and the configuration of at least one member carrier accords with the uplink-downlink configuration of an R8; and issuing the uplink-downlink configuration of any member carrier and the uplink-downlink configuration of other member carriers of any member carrier aggregation into an LTE-A user terminal UE. The invention also provides an uplink-downlink configuration receiving method of the TDD system carrier aggregation. The invention can realize the uplink-downlink configuration in the LTE-A system so as to be suitable for TDD system requirements.

Description

technical field [0001] The present invention relates to carrier aggregation technology, in particular to an uplink and downlink configuration and receiving method of time division duplex (TDD) system carrier aggregation. Background technique [0002] The LTE-Advanced (LTE-A for short) system can support a wider system bandwidth than the Long Term Evolution (LTE) system, such as 100 MHz. Specifically, resources of multiple LTE carriers (also known as component carriers) can be connected together to provide wider system bandwidth for LTE-A UEs, where LTE-A UEs are terminal devices in the LTE evolved system and can be used in It works in the LTE-A system and can support new functions provided by the LTE-A system. Specifically, the LTE-A system has two ways to connect multiple LTE carrier resources, one is to aggregate multiple continuous LTE carriers, and the other is to aggregate multiple discontinuous LTE carriers, both of which can be LTE-A A provides greater transmission ...
