That is, in some embodiments of the invention, after terminal is the symbolic number for determining DMRS the step of, may be used also To determine the pattern of DMRS according to the symbolic number of DMRS, and according to the pattern of DMRS, carry out the transmission of PUCCH information.

The pattern of DMRS includes the symbolic number of DMRS and DMRS is mapped to the position of physical resource, the embodiment of the present invention In, it is preferable that the position that DMRS is mapped to physical resource can be arranged by agreement.Or the DMRS is mapped to physics money The position in source can also dynamically or semi-statically be indicated by base station.

The relationship of above-mentioned configured transmission and DMRS symbolic number is illustrated in turn below.

(1) the UCI charge number range of PUCCH carrying

In the embodiment of the present invention, the UCI charge number range of PUCCH carrying can be by base station according to the transmission for being indicated to terminal (TM) mode determines.

The transmission mode, which for example can be, sends diversity or spatial reuse etc..For example, at this time when sending diversity Required UCI charge number is smaller, and supports the transmission of 16 or more layers in spatial reuse, and required UCI charge number is larger at this time.

For example, UCI charge number can be divided into two sections, the UCI charge number category less than or equal to 60bits In a charge number range (being properly termed as side crops industry range), the UCI charge number greater than 60bits belongs to a charge number range (being properly termed as big load range).Certainly, the method for dividing UCI charge number range is not limited to this.

In the embodiment of the present invention, it is preferable that according to the configured transmission that base station configures, the step of determining the symbolic number of DMRS packet It includes: according to the configured transmission for the UCI charge number range for including at least PUCCH carrying, determining the symbolic number of DMRS, wherein determine DMRS corresponding with the UCI charge number range numerical value of symbolic number it is negatively correlated.

So-called negative correlation refers to the increase with the corresponding numerical value of UCI charge number range, and the symbolic number of DMRS reduces.Also It is to say, the corresponding numerical value of UCI charge number range number is bigger, and the symbolic number of DMRS reduces.The corresponding numerical value of UCI charge number range number Smaller, the symbolic number of DMRS subtracts greatly.It, can be with when the symbolic number of DMRS is smaller when the corresponding setting of UCI charge number range number is larger UCI load is carried using more resource, advantageously reduces the code rate of coding, promotes the performance of coding.When UCI charge number model It is smaller to enclose corresponding numerical value, it, can (also referred to as DMRS's be close according to more DMRS symbolic number when the symbolic number of DMRS is larger Degree), the performance of Lai Tisheng channel estimation.

In some currently preferred embodiments of the present invention, above-mentioned basis includes at least the transmission ginseng of the UCI load of PUCCH carrying The step of counting, determining the symbolic number of DMRS may include: when the UCI load range is the range less than or equal to preset threshold When, determine that the symbolic number of DMRS is the first numerical value；When the UCI load range is the range greater than the preset threshold, really The symbolic number for determining DMRS is second value, wherein second value is less than first numerical value.

The preset threshold can according to need determination, such as can be 60bits, and first numerical value can be 4, institute Stating second value can be 2.

Referring to FIG. 2, for example, in one embodiment of this invention, the symbolic number of PUCCH is 14, please refer in Fig. 2 (a), when the charge number range of UCI is greater than the range of 60bits, the symbolic number of DMRS is 2.Please refer in Fig. 2 (b) and (c), when the charge number range of UCI is less than the range equal to 60bits, the symbolic number of DMRS is 4.And (b) and the area of (c) It is not, the position that DMRS is mapped to physical resource is different, and the position that DMRS is mapped to physical resource can be by protocol conventions.Or The position of person DMRS can also dynamically or semi-statically be indicated by base station.

Requirement due to each content type to Block Error Rate (BLER) may be different, thus can be considered using different The symbolic number of DMRS.

That is, in the embodiment of the present invention, can according to the configured transmission of the content type for the UCI for including at least PUCCH carrying, Determine the symbolic number of DMRS.

For example, in some embodiments, ACK/NACK, RI, SR etc. to the more demanding of BLER, such as are wanted Seek BLER=1%；For CQI and PMI etc., the requirement to BLER is lower, such as requires BLER=10%.

Thus, in some currently preferred embodiments of the present invention, with specific reference to the content for the UCI for including at least PUCCH carrying The configured transmission of type, the method for determining the symbolic number of DMRS may is that

When the content type of UCI includes first kind content, when not including Second Type content, the symbolic number of DMRS is determined For third value, the first kind content includes at least one of ACK/NACK, RI and SR, the Second Type content packet Include at least one of CQI and PMI；

When the content type of UCI includes that the Second Type content determines DMRS when not including the first kind content Symbolic number be the 4th numerical value, the 4th numerical value be less than the third value；

When the content type of UCI includes first kind content and Second Type content, determine that the symbolic number of DMRS is the Three numerical value or the 4th numerical value.

That is, can be adopted for ACK/NACK, RI and SR etc. to the content type of the more demanding UCI of BLER With the performance of the symbolic number of biggish DMRS (using higher DMRS density) Lai Tisheng channel estimation, and, for CQI and The content type of the lower UCI of the requirement to BLER such as PMI, can be using the symbolic number of lesser DMRS (i.e. using lower DMRS density, more UCI resource), to reduce the code rate of coding, promote the performance of coding.

And for containing the UCI of first kind content and Second Type content simultaneously, it can according to need selection DMRS Symbolic number.For example, can be with reference to the other parameters in the configured transmission, to determine the symbolic number of DMRS.
