Description

Signal transmitting method and user equipment, storage medium Technical field

The present invention relates to a channel sounding reference signal (SRS) technology in the field of wireless communications, and in particular, to a signal transmitting method, a user equipment, and a storage medium.

Background technique

With the development of wireless communication technologies, very high transmission rates have been proposed in different fields and in different scenarios, so that certain special scenarios, such as high-speed scenes and route scenarios, require relatively high frequency synchronization problems. If the center frequency is high or high, the Doppler frequency offset problem in high-speed scene will seriously affect the system performance, especially how to solve the problem of frequency offset estimation brings great challenges.

For the problem of frequency offset measurement, although many methods have been proposed in the industry, there are many problems, especially when the frequency offset value is large, or the estimation accuracy is poor, or the frequency offset tracking speed is slow. Can not solve the problem of frequency offset better. According to the traditional idea, SRS is used for frequency offset measurement, and there is a problem of poor estimation accuracy, which is difficult to meet the requirements of measurement accuracy.

Due to the shortage of spectrum resources, the utilization of spectrum resources has also become an important concern. However, various measurement requirements require a certain amount of resources for the transmission of pilot data, which undoubtedly leads to a decrease in resource utilization. When SRS is periodically transmitted, if we need to set the period to be small in a certain period of time in order to meet some measurement requirements, if the terminal always transmits according to this configuration, it is undoubtedly a greater waste of resources.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings.

Embodiment 1

The embodiment provides a signal sending method, which is applied to a user equipment. As shown in FIG. 1 , the method includes:

Step 101: Receive a first configuration parameter sent by a base station.

Step 102: Determine a period corresponding to the first configuration parameter according to a correspondence between a configuration parameter and a period.

The period includes a first period in which the SRS is transmitted through the special subframe and a second period in which the SRS is transmitted through the normal subframe.

Step 103: Send the SRS through the special subframe in the first period, and/or send the SRS through the normal subframe in the second period.

2 is a schematic diagram of SRS transmission on a special subframe. In FIG. 2, user equipment 1 and user equipment are interleaved to occupy a special subframe.

This embodiment provides two ways to send a period. In the first mode, the SRS transmission needs to be triggered multiple times, and the second method needs to trigger an SRS transmission.

The first mode is: when the second period is greater than the first period, the first period is used as the sending period; in the sending period, the triggering is sent by using the special subframe; when the SRS is sent through the special subframe, Modifying the transmission period to a second period; after the modified transmission period Internally, the trigger transmits the SRS through the normal subframe.

For example, in this embodiment, two consecutive SRS symbols are sent in the first period of the sending period, that is, the SRS transmission is triggered, and the sending period is modified to the second period, and the second period is greater than the first period. Preferably, the first period is 2 ms. It is worth noting that the configuration period can be modified to 2ms when the frequency offset measurement is needed again. If the frequency offset measurement is not needed, the cycle reconfiguration is performed.

Here, in this embodiment, the SRS can be triggered by the two triggering modes. The first triggering mode is to trigger the sending of the SRS by using the high layer signaling sent by the base station. Specifically, the user equipment initiates a reconfiguration request to the upper layer (base station), or the lower layer of the base station sends a reconfiguration request to the upper layer, and the upper layer reconfigures the sending period according to the reconfiguration request, that is, when the sending period is the first period, the sending period is The second triggering mode is changed to the second cycle, and vice versa. The second triggering mode is that the base station triggers the user equipment to send the SRS by using Downlink Control Information (DCI). In the prior art, the triggering SRS transmission is performed by using DCI, mainly for non-periodic SRS transmission.

By way of example, the present invention also proposes to trigger a SRS transmission by means of DCI triggering. The specific implementation may be triggered by the DCI when the frequency offset value of the maintenance needs to be updated, or when the frequency offset measurement is required. There are three types of first cycles that can be selected in this trigger mode, namely 2ms, 5ms and 10ms. The specific selection can be determined according to the measurement requirements, and no limitation is imposed here. Considering the requirement of supporting large frequency offset measurement at high speed, it is preferably 2ms from the perspective of frequency offset measurement, and is transmitted on two consecutive symbols on UpPTs subframe (special subframe), so that the maximum frequency can be guaranteed. The need for partial measurement. It is worth noting that for SRS transmission on a special frame, we can configure a minimum period of 2ms, which means that we can send two consecutive SRS symbols on a special subframe on one field.

The second way is:

The second method can be divided into two types according to the different enabling modes.

The first type of enabling includes: receiving an enable control instruction sent by the base station through the high layer signaling, the enable control instruction is used to enable the period of the control; and when the enable control instruction indicates the second period When the power is enabled, the SRS is sent through the normal subframe in the second period; when the enable control command indicates that both the second period and the first period are enabled, the SRS is sent through the special subframe in the first period, and in the second The SRS is transmitted through the normal subframe during the period.

Preferably, the second period of FIG. 2 is a sub-period within the first period.

The second enabling mode includes: determining whether the first period is smaller than the second period; if the first period is equal to the second period, indicating that the second period is enabled, the first period is not enabled; and the normal period is passed during the second period. The frame sends the SRS; if the first period is smaller than the second period, it means that both the first period and the second period are enabled; in the first period, the SRS is sent through the special subframe, and the second period is sent through the normal subframe. SRS.

For the second mode, preferably, the second period is a sub-period within the first period.

Further, in the second mode, the step 103 further includes: acquiring a frequency domain start position of the first period and the second period; and transmitting, in the first period, the SRS in the frequency domain start position of the first period. In the second period, the SRS is transmitted at the frequency domain start position of the second period.

Specifically, if the second period is enabled, the two-cycle SRS can be simultaneously enabled with frequency hopping, or the frequency hopping is not enabled at the same time, or one of the two periods can be enabled for frequency hopping. One cycle hopping is not enabled.

If the second period of the SRS is enabled, the related parameters of the second period may be consistent with the first period, and the related parameters of the corresponding period may be inconsistent by the higher layer signaling; therefore, the configuration parameters are the same. In this case, the frequency domain start position of the second period may remain consistent with the first period, or may remain inconsistent with the first period. Preferably, the comb tooth positions (frequency domain start positions) of the two SRSs corresponding to the first period are inconsistent, that is, when

with

In the same situation,

In case of inconsistency, the comb tooth positions of the two SRSs are staggered, and the frequency domain start positions for acquiring the first period and the second period include:

Obtaining a frequency domain start position of the first period and the second period, where the frequency domain starts

Here, the second period in this embodiment is one sub-period in the first period, that is, when the SRS is transmitted through the special subframe in the first period, the second period transmits the SRS through the normal subframe. As shown in FIG. 2, the time period of the first cycle includes the time period of the second cycle. FIG. 2 is an exemplary illustration, and the start time of the detection may be different or the same.

Correspondingly, the user equipment receives the relevant parameters of the first period, the second period, and the two, and assumes that the calculated starting positions of the frequency domains defined by the two user equipments are 0 and 1, respectively, and the special in the first period The frequency domain start positions corresponding to the two SRS symbols of the subframe are 1 and 0, respectively, as shown in FIG. 3, so that two SRS symbols on the UpPTs of the subframe 0 perform corresponding user positions on the two resource locations. SRS pilot data mapping. The two user equipments detect the frequency offset value on the first period and the second period. Here, the method for detecting the frequency offset value is the same as the prior art, and this embodiment will not be described in detail.
