Description
Technical field
The present invention relates to the communications field, send the method that order is indicated (Rank Indication, RI) in a kind of capable physically shared channel.
Background technology
Be a kind of multi-carrier modulation communication technology on OFDM (Orthogonal Frequency Division Multiplexing, OFDM) technological essence, this technology is one of core technology in the 4th third-generation mobile communication.On frequency domain, the multipath channel of OFDM presents the frequency selective fading characteristic, in order to overcome this decline, channel is divided into a plurality of subchannels on frequency domain, the spectral characteristic of every sub-channels is near flat all, and each sub-channels of OFDM is mutually orthogonal, therefore allows the frequency spectrum of subchannel overlapped, thereby can very large limit land productivity frequency spectrum resource.
Multiple-input and multiple-output (Multiple Input Multiple Output, MIMO) technology can increase power system capacity, improve transmission performance, and can finely merge with other physical-layer techniques, therefore becomes the key technology of B3G and 4G mobile communication system.But when channel relevancy was strong, the diversity gain and the spatial multiplexing gain that are brought by multipath channel reduced greatly, cause declining to a great extent of mimo system performance.Propose in recent years a kind of new MIMO method for precoding, the method is a kind of efficient MIMO multiplex mode, and its precoding processing by the sending and receiving end changes into a plurality of independently pseudo channels with mimo channel.Because effectively eliminated the impact of channel relevancy, so precoding technique has guaranteed the stability of mimo system under various environment.
Long Term Evolution (Long Term Evolution, LTE) system is the essential planning of third generation partnership.the realization of precoding technique in LTE is by at subscriber equipment (UE) and base station (eNodeB), code book (set of pre-coding matrix) being set, UE according to certain criterion (for example, throughput-maximized or near the right singular matrix of channel matrix) select best pre-coding matrix from code book, and with pre-coding matrix index (Precoding MatrixIndex, PMI) feed back to eNodeB, eNodeB seeks corresponding pre-coding matrix according to the PMI that receives in code book, use this pre-coding matrix and carry out the precoding transmission in downlink.And, also need to feed back the RI signaling in up channel, this denoting signaling the maximum symbol quantity that can transmit on subcarrier.
Stipulate in the LTE system, when the targeted customer feeds back the RI signaling, if this targeted customer does not need to send data, the RI signaling is at PUCCH (Physical Uplink ControlChannel, Physical Uplink Control Channel) transmission in, if this targeted customer need to send data, RI signaling transmission in PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel).
At present, be defined in PUSCH the RI signaling at next-door neighbour ACK (Acknowledge, correctly reply)/NACK (Non-Acknowledge, wrong responses) transmit on the OFDM symbol of signaling, and the ACK/NACK signaling is transmitted on the OFDM symbol of next-door neighbour's upstream data pilot tone, Fig. 1 and Fig. 2 have provided respectively (the Normal CyclicPrefix at Normal CP, the regular circulation prefix) and Extended (Extended, expansion) during CP, RI signaling and the transmission location of ACK/NACK signaling in PUSCH.
In realizing process of the present invention, the inventor finds as depicted in figs. 1 and 2, transmits on sounding (detection) pilot tone last OFDM symbol in subframe, and when expansion CP, sounding pilot tone and RI signaling can send on same symbol like this.This makes the RI signaling can be subject to the interference of same other user's of residential quarter sounding pilot tone, has affected the transmission performance of RI signaling, causes the entire system performance to descend.
Summary of the invention
The present invention aims to provide a kind of sending method of going physically rank indication signaling in shared channel, with the sounding pilot tone that the solves prior art problem that affects on the RI signaling.
In an embodiment of the present invention, provide a kind of sending method of going physically rank indication signaling in shared channel, comprised the following steps: the RI signaling has been arranged in subframe on the OFDM symbol different from Sounding pilot tone place OFDM symbol; Send this subframe in capable physically shared channel.
Above-described embodiment go physically the sending method of rank indication signaling in shared channel because suitably be provided with the OFDM symbol at RI signaling place, so overcome the affect problem of sounding pilot tone on the RI signaling, thereby the assurance system overall performance.
