Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described.

Embodiment one

The present embodiment provides a kind of signaling method, applied to user equipment, as shown in figure 1, this method includes：

Step 101, the first configuration parameter for receiving base station transmission.

Step 102, the corresponding relation according to configuration parameter and cycle, determine the first configuration parameter corresponding cycle.

The cycle includes sending SRS period 1 by special subframe and sends the SRS's by normal sub-frames Second round.

Step 103, within the period 1 SRS sent by special subframe, and/or pass through within second round normal sub-frames Send SRS.

Fig. 2 is that user equipment 1 and user equipment occupancy of interlocking are special in the schematic diagrames that are transmitted on special subframe of SRS, Fig. 2 Subframe.

The present embodiment provides two ways to send the cycle, first way needs repeatedly triggering SRS transmission, second Need to trigger a SRS transmission.

First way is：When second round being more than the period 1, the period 1 cycle of transmission will be used as；In hair Send in the cycle, triggering sends the SRS by special subframe；After SRS is sent by special subframe, by the transmission cycle It is revised as second round；In the transmission cycle after the modification, triggering sends SRS by normal sub-frames.

Example, the present embodiment sends two continuous SRS symbols within the period 1 as the cycle of transmission, that is, triggers SRS transmissions, the transmission cycle is revised as second round, and second round is more than the period 1.It is preferred that, the period 1 is 2ms. What deserves to be explained is, configuration cycle is revised as 2ms when can needing to carry out frequency deviation measurement again, if not needing frequency deviation measurement When enter line period and match somebody with somebody again.

Here, the present embodiment can send SRS by two kinds of triggering mode triggerings again, and the first triggering mode is by base The high-level signaling triggering sent of standing sends SRS.Specifically, user equipment is initiated again with request, or base station to high-rise (base station) Low layer is initiated again with request to high level, high-rise according to reconfiguring the transmission cycle with request again, that is to say, that to be when the transmission cycle During the period 1, the transmission cycle is changed to second round, vice versa；Second of triggering mode is that base station is believed by descending control Cease (Downlink Control Information, DCI) triggering user equipment and send SRS.In the prior art, using DCI's Mode carries out triggering SRS and sent, primarily directed to aperiodic SRS transmission.

Example, the present invention by the way of DCI is triggered it is also proposed that carry out triggering SRS transmission.Implementing can basis When the frequency deviation value of maintenance needs to update, need touched by way of sending out DCI when frequency deviation measurement in other words Hair sends SRS.There are three kinds, i.e. 2ms, 5ms and 10ms the selectable period 1 under this triggering pattern, it is specifically chosen can basis Measurement request is determined, is not limited herein.In view of the requirement for the measurement for needing to support big frequency deviation under high-speed case, from frequency Measurement angle partially considers preferred 2ms, and is transmitted on continuous two symbols in UpPTs subframes (special subframe), so It equally ensure that the demand of maximum frequency deviation measurement.What deserves to be explained is, during for sending SRS in special frames, our most I To be configured to 2ms cycle, that is to say, that we can send continuous two SRS symbols on special subframe on a field Number.

The second way is：

The second way can be divided into two kinds again according to the difference of the mode of enable.

The first enable mode includes：Receive the enable control instruction that base station is sent by high-level signaling, the enable control Enable of the system instruction for controlling cycle；When enabling control instruction instruction second round enable, by just within second round Normal subframe sends the SRS；When enabling control instruction instruction second round and the period 1 all enables, lead within the period 1 Cross special subframe and send SRS, SRS is sent by normal sub-frames within second round.

It is preferred that, such as Fig. 2 second rounds are a minor cycles within the period 1.

Second of enable mode includes：Judge whether the period 1 is less than second round；If the period 1 is equal to second week Phase, then it represents that second round enables, the period 1 does not enable；Within second round the SRS is sent by normal sub-frames；If the One cycle was less than second round, then it represents that period 1 and second round all enable；Sent out within the period 1 by special subframe SRS is sent, SRS is sent by normal sub-frames within second round.

For the second way, it is preferred that second round is a minor cycle within the period 1.

Further, for the second way, step 103 specifically also includes：Obtain the frequency of period 1 and second round Domain original position；Within the period 1, SRS is sent in the frequency domain original position of period 1；Within second round, The frequency domain original position of two cycles sends SRS.

If specifically, in the case of second period enable, the SRS in two cycles frequency hopping can be enabled, and also may be used simultaneously Do not enabled with frequency hopping simultaneously, a cycle frequency hopping that can also be in two cycles is enabled, and another cycle frequency hopping is not enabled.

If in the case that SRS second round enables, the relevant parameter of second round can be kept and a cycle It is consistent, can also be issued by high-level signaling correspondence the cycle relevant parameter it is inconsistent；Therefore, in configuration parameter identical feelings Under condition, the frequency domain original position of second round can keep consistent with the period 1, can also keep with the period 1 not Unanimously.It is preferred that, period 1 corresponding two SRS broach position (frequency domain original position) is inconsistent, that is to say, that whenWithIn the case of identical,Situation, if inconsistent, two SRS broach position is staggered, described Obtaining the frequency domain original position of period 1 and second round includes：

Obtain the frequency domain original position of period 1 and second round, the frequency domain original positionMeet：
