Embodiment 1

[0044] When extending CP, according to method 1, uplink data pilots are transmitted on the third and ninth OFDM symbols in the uplink subframe, and ACK / NACK signaling is transmitted on the second, fourth, and ninth OFDM symbols in the uplink subframe. The eighth and tenth OFDM symbols are transmitted, and the RI signaling is transmitted on the fifth, sixth, seventh and eleventh OFDM symbols in the uplink subframe, such as Figure 4 shown;

Embodiment 2

[0046] When extending CP, according to method 2, uplink data pilots are transmitted on the third and ninth OFDM symbols in the uplink subframe, and ACK / NACK signaling is transmitted on the second, fourth, and ninth OFDM symbols in the uplink subframe. The eighth and tenth OFDM symbols are transmitted, and the RI signaling is transmitted on the first, fifth, sixth and seventh OFDM in the uplink subframe, such as Figure 5 shown;

Embodiment 3

[0048] When extending CP, according to method three, uplink data pilots are transmitted on the third and ninth OFDM symbols in the uplink subframe, and ACK / NACK signaling is transmitted on the second, fourth, and ninth OFDM symbols in the uplink subframe. The eighth and tenth OFDM symbols are transmitted, and the RI signaling is transmitted on the fifth, sixth and seventh OFDM in the uplink subframe, such as Figure 6 shown;

Abstract

The invention provides a method for sending rank indication singling in a sharing channel on a physical uplink, which comprises the following steps of: arranging RI singling in a subframe on OFDM symbols different from OFDM symbols where sounding pilot is, and sending the subframe in the sharing channel on the physical uplink. The sending method of the invention can prevent the sounding pilot from affecting the RI singling and dose not reduce decoding performance of the RI singling, thus ensuring the integral performance of the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for sending Rank Indication (RI) in a physical uplink shared channel. Background technique [0002] Orthogonal Frequency Division Multiplexing (OFDM) technology is essentially a multi-carrier modulation communication technology, which is one of the core technologies in the fourth generation mobile communication. In the frequency domain, the OFDM multipath channel exhibits frequency-selective fading characteristics. In order to overcome this fading, the channel is divided into multiple sub-channels in the frequency domain. The spectral characteristics of each sub-channel are approximately flat, and each sub-channel of OFDM The channels are orthogonal to each other, so the spectrums of the sub-channels are allowed to overlap each other, so that the spectrum resources can be utilized to the greatest extent. [0003] Multiple Input Multiple Output (MIMO) technology can inc...
