Specific embodiment
As it was previously stated, in big bandwidth scenarios, the transmission range of existing channel-sounding signal transmission method is smaller.
Existing LTE generally carries out SRS transmission using in the following manner, and one of which is to take a symbol, using frequency domain
Continuous sequence long is transmitted；Another kind is to take multiple symbols, is transmitted using the continuous short sequence of frequency domain.Above-mentioned two
Kind of transmission means typically each realizes that frequency domain maps in the form of comb, specifically may refer to Fig. 1 a and Fig. 1 b, wherein legend 11,
12nd, 13,14 different comb is represented respectively.
Fig. 1 a indicate the situation that comb is 2, namely 1 subcarrier in interval carries out frequency mapping；Fig. 1 b sign comb is 4
Situation, namely 3 subcarriers in interval carry out frequency domain mapping.
Studied through inventor and found, under big bandwidth scenarios, such as 5G scenes, due to being limited by terminal power, if
A symbol is taken, the mode being transmitted using the continuous sequence long of frequency domain occurs that the power spectrum of channel-sounding signal is close
Spend low, transmission range is smaller, it is impossible to meet the problem of covering demand；If being transmitted using the continuous short sequence of frequency domain,
Need to take multiple symbols, it is impossible to meet the demand of flexible configuration.
In embodiments of the present invention, network side is wide interior for transmitting by the first frequency domain pattern index strip of resource block level
The Resource Block of channel-sounding signal, terminal uses the resource of the first frequency domain pattern instruction according to the instruction of network side
Block carries out the transmission of channel-sounding signal.Due in embodiments of the present invention, channel-sounding signal being carried out in resource block level
Transmission, and the non-immediate subcarrier transmission channel detectable signal in Resource Block, therefore terminal can carry out channel spy with concentration power
Survey the transmission of signal, and then the distance of effective transmission channel detectable signal with hoisting power spectrum density, can be increased, further can be with
The scope of lifting effectively transmission.
Further, configuration information also includes the other second frequency domain pattern of sub-wave length, and the second frequency domain pattern indicates the money
For the subcarrier of transmission channel detectable signal in source block, the son that terminal can also be indicated using the second frequency domain pattern
Carrier wave carries out the transmission of channel-sounding signal, so that based on channel-sounding signal to the subcarrier for transmission channel detectable signal
Subcarrier detected, carry out the other flexible configuration of sub-wave length.
Additionally, network side is believed according to terminal in the channel detection that the Resource Block that the first frequency domain pattern is indicated sends
Number determine target resource block, the second frequency domain pattern only indicates the subcarrier for transmission channel detectable signal in target resource block,
Therefore with hoisting power spectrum density, can further lift the transmission range of channel-sounding signal transmission method.
It is understandable to enable above-mentioned purpose of the invention, feature and beneficial effect to become apparent, below in conjunction with the accompanying drawings to this
The specific embodiment of invention is described in detail.
Fig. 2 is a kind of flow chart of the transmission method of channel-sounding signal in the embodiment of the present invention, it is adaptable to terminal, can be with
Comprise the following steps：
