Specific embodiment

For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing and specifically The present invention is described in further detail for embodiment.It should be noted that in the case of not conflicting, Embodiment in the application and the feature in embodiment can mutual combination in any.

Specific embodiment one

Terminal starts one of in the following manner the channel measurement of pucchformat1/1a/1b channel or prelists The transmission process of code selection signal:

Mode one: terminal receives its corresponding pdsch transmission in the n-th subframe, and terminal is in the (n+1)th son Frame starts its channel measurement or the transmission process of precoding selection signal；

Mode two: after terminal and server sync, terminal periodic is obtained by high-level signaling and carries out The channel measurement of pucchformat1/1a/1b channel or the transmission of precoding selection signal, terminal is in subframe N starts channel measurement or precoding selection signal transmission process, and wherein n meets n mod t=m, wherein t For carrying out the cycle of channel measurement or precoding selection, m is sub-frame offset, m ∈ (0,1 ..., t-1 }, Cycle t can be according to system bandwidth determine fixed value or high-level signaling notify value, m Notified by high-level signaling.Now cycle t is greater than this channel measurement shared used or precoding selects resource User complete the minimum duration that a channel measurement or precoding select to need；

Mode three: high-level signaling notifies terminal to start pucchformat1/1a/1b channel in the n-th subframe Channel measurement or the transmission of precoding selection signal；

Mode four: by dynamic signaling dci (downlinkcontrolinformation, Downlink Control Information) Triggering terminal starts the channel measurement of pucchformat1/1a/1b channel in the n-th subframe or precoding selects The transmission of signal；Such as ue receives the letter starting pucchformat1/1a/1b channel in the n-th-k subframe Road measurement or the dci signaling of precoding selection signal transmission process, terminal starts in the n-th subframe The channel measurement of pucchformat1/1a/1b channel or precoding selection signal transmission process, k value is more than Equal to 1, it is a fixed value.

Specific embodiment two

Terminal starts the transmission of channel measurement or precoding selection signal in the n-th subframe, sends out in the n-th subframe Channels measurement or precoding selection signal, but because a tti interior energy gives the channel of a terminal Measurement or precoding select resource-constrained so that terminal can not complete whole channel measurements in a tti Or the transmission of precoding selection signal, that is, base station side can not obtain whole physic channel informations, or entirely The receptivity of the possible wave beam in portion, thus base station side can not obtain optimum precoding or optimum precoding sequence Arrange, now base station side needs to select reference signal information based on the channel measurement on multiple tti or precoding, Could obtain whole physical channels, or all may wave beam receptivity, then just can obtain Excellent precoding or optimum precoded sequence, are fed back to terminal.

Terminal after channel measurement or precoding select to start, the n-th subframe described channel measurement or Precoding selects to send channel measurement or precoding selection signal in resource, needs to be spaced t_gapIndividual subframe, I.e. in n+t_gapChannel measurement and precoding selection signal that subframe does not distribute, wherein tg_apRepresent eventually Minimum interval between the channel measurement signal transmission twice of end, unit is transmission cycle tti (transimissiontimeinterval, transmission intercal)..

The physical port of such as terminal is 6, and a channel measurement resource corresponds to a physical port, terminal Need to occupy 6 channel measurement resources, but in a tti, distribute to the channel measurement resource of this terminal Only 2, then terminal needs, after 3 channel measurement subframes, just to complete whole channel measurements The transmission of signal, base station, based on the channel measurement reference signal in these channel measurement resources, obtains physics Channel h, and then obtain precoding selection result, in a stator frame, precoding selection result is fed back to end End, one time channel measurement process terminates.

After channel measurement or precoding selection startup, only carry out a channel measurement or precoding choosing Select signal transmission process.

As shown in figure 1, when the cycle starts the channel measurement process of pucchformat1/1a/1b, n-th After individual subframe starts channel measurement, every t_gapIndividual subframe transmitting portion channel measurement signal, a cycle After interior 3 secondary channel measurement subframes, complete the transmission of whole channel measurement signal.Base station side is based on these The channel measurement reference signal in channel measurement resource in channel measurement subframe, obtains physical channel measurement, And then obtain precoding selection result.In subsequent subframe, precoding selection result is fed back to terminal.Or Person is fed back by high-level signaling, or is fed back by dynamic signaling, wherein last channel measurement subframe Interval and feedback subframe between can be fixing it is also possible to not fix.T is channel measurement cycle, week Phase has arrived a new afterwards channel measurement process and has started.

If otherwise starting channel measurement or precoding selection signal transmission process, complete once After channel measurement or precoding selection, channel measurement to be launched or precoding selection signal to be waited to be transmitted across The event of journey occurs just to carry out the transmission of new channel measurement or precoding selection signal.

Specific embodiment three

In prior art, pucchformat1/1a/1b is to be multiplexed by cs in frequency domain, passes through in time domain Orthogonal code is multiplexed, due to the symbol numbers of pucchformat1/1a/1b time domain and the time domain symbol of dmrs Number number difference, pucchformat1/1a/1b does not reach the limit of multiplexing in time domain, also remaining, Because channel measurement or precoding select not needing dmrs (demodulationreferencesignal, demodulation Reference signal), now can utilize these remaining time domain orthogonal codes.

For normalcp because one time slot of time domain dmrs reference signal only has 3, thus same Cs at most can only be multiplexed 3 pucchformat1/1a/1b channels in time domain, and channel measurement or prelist Code selection signal without dmrs as channel estimation reference signal it is possible to show unused in the protocol Orthogonal code sequence, i.e. [1,1, -1, -1], if now running into the 2nd time slot is short format, just unusable This sequence, can select not sending corresponding channel measurement or precoding selection signal, if there are other letters Road measurement or precoding select subframe, then base station side equally can obtain precoding selection result.Than strictly according to the facts Apply example two, one time channel measurement process needs 3 channel measurement subframes, if only 1 subframe is short Form, then base station side still can be obtained based on the channel measurement signal that other channel measurement subframes send The precoding selection result of suboptimum.If all channel measurements of a terminal or precoding select subframe all There is the transmission of srs, be now accomplished by high-rise configuration, it is to avoid carry out channel measurement in these subframes or prelist Code selects.

For extension cp, now because dmrs can only be multiplexed 2 in time domain, so Pucchformat1/1a/1b now can only be multiplexed 2, and sequence is orthogonal code 0 and orthogonal code 2, I.e. [1,1,1,1] and [1, -1, -1,1], now channel measurement or precoding select resource just can use unused sequence, I.e. orthogonal code 1 and orthogonal code 3, i.e. [1, -1,1, -1] and [1,1, -1, -1], at this point for the 2nd time slot if short Form is it is possible to [1, e^j2π/3, e^j4π/3], or do not send out.
