Embodiment Construction

[0038]The core idea of ​​the present invention is: after the aggregated carrier frequency is divided into more than one component carrier frequency, the data carried by the physical channel or the Sounding (measurement) pilot signal are frequency-hopped and transmitted among the component carrier frequencies.

[0039] The frequency hopping transmission refers to: which component carrier frequency is not fixed for data transmission, which is configured by the base station.

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] Such as Figure 6 As shown, Embodiment 1 of the present invention includes the following steps:

[0042] Step 601, the base station divides the aggregated carrier frequency into more than one component carrier frequency;

[0043] Step 602, the base station reconfigures the component carrier frequency where the data carried by the physical channel is located;

Abstract

The present invention provides a data transmitting method in a wider bandwidth system, which includes: an aggregate carrier frequency is divided into more than one component carrier frequency, data carried through a physical channel or a measuring pilot signal is transmitted between the component carrier frequencies in a frequency hopping manner. The present invention can ensure compatibility between a LTE-Advanced system and a LTE-Release-8 system, facilitate an increase of system capacity and scheduling flexibility of the LTE-Advanced system, and enable a LTE-Advanced terminal to obtain maximum frequency-selection gain.

Description

technical field [0001] The invention relates to the field of mobile wireless communication, in particular to a method for data transmission in a large bandwidth system. Background technique [0002] In the frame structure of LTE (Long Term Evolution, long-term evolution) system FDD (Frequency Division Duplex, Frequency Division Duplex) mode, a 10ms radioframe (wireless frame) consists of twenty slots ( time slot), and time slot 2i and 2i+1 form a subframe (subframe) i with a length of 1ms, such as figure 1 shown. In the frame structure of LTE system TDD (Frequency Division Duplex, Frequency Division Duplex) mode, a 10ms radio frame (wireless frame) is composed of two halfframes (halfframes) with a length of 5ms, and a halfframe contains five halfframes with a length of 1ms. The subframe (subframe), subframe i is defined as two time slots 2i and 2i+1 with a length of 0.5ms, such as figure 2 shown. In the two frame structures, for Normal CP (Normal Cyclic Prefix, standard...
