Embodiment Construction

[0101] The present invention provides a method for sending uplink detection pilots. By sending CS pilot scheduling signaling to a terminal, the terminal sends uplink detection pilots according to the instructions in the CS pilot scheduling signaling.

[0102] It should be noted that those skilled in the art should know that the CS pilot scheduling signaling here is not limited to the aforementioned signaling indicating the CS pilot transmission frequency band, but includes information related to CS pilot transmission.

[0103] In the current LTE standard, there are already tendentious opinions on the transmission of CS pilots in the FDD mode. In order to introduce the CS pilot transmission scheme under FDD, the frame structure of FDD is firstly introduced below.

[0104] figure 2 The frame structure of the FDD scheme is shown. Such as figure 2As shown, one frame includes 20 subframes of equal length. The duration of two subframes is a transmission time interval (Transmis...

Abstract

The invention discloses a method, system, base station and terminal for transmitting ascending detecting pilot frequency. The method is applied in long term development plan, which includes: transmitting ascending detecting pilot frequency scheduling signaling to terminals; the terminals transmitting the ascending detecting pilot frequency according to the indication in the ascending detecting pilot frequency scheduling signaling. The ascending detecting pilot frequency scheduling signaling includes assembly of one or a plurality of transmitting starting time, transmitting cycles, duration time, sub-carrier numbers, time slot number, long block number, frequency band and the like indication information of the ascending detecting pilot frequency. Use of the invention, can dynamically schedule the terminal for transmitting the ascending detecting pilot frequency, and gives out a scheme for carrying ascending detecting pilot frequency scheduling signaling, and also gives out a scheme for determining the position of the sub-frame the ascending detecting pilot frequency locates, so that the position of the sub-frame the ascending detecting pilot frequency locates can furthermore accurately reflect the channel situation of the ascending / descending process according to the ascending detecting pilot frequency.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for sending an uplink detection pilot, a base station and a terminal. Background technique [0002] In order to meet the ever-increasing demands in mobile communication systems, especially for higher data rates, lower latency, improved system capacity and coverage, the Third Generation Partnership Project (The3 rd The Generation Partner Project, 3GPP) organization has launched a Long Term Evolution (Long Term Evolution, LTE) plan. [0003] In the developing Long Term Evolution (LTE) plan, all users share physical resources, and the physical resources are allocated and scheduled by the base station. The LTE includes a data demodulation (Data deModulation, DM) pilot for providing uplink channel estimation, uplink coherent demodulation, and detection information similar to the uplink pilot in the existing 3G system. In addition to DM pil...
