Embodiment 1

[0065] An embodiment of the present invention provides a method for determining a PUCCH power control offset, which can be applied to a terminal, such as a mobile phone, a tablet computer, a personal computer, a notebook computer, a wearable electronic device, and other devices with communication functions.

[0066] See figure 1 , the flow of the method for determining the PUCCH power control offset in the embodiment of the present invention is described as follows.

[0067] Step 101: Determine the number of bits 0 of the first UCI that needs to be transmitted on the PUCCH UCI , and determine the number N of REs carrying the first UCI in the PUCCH RE .

[0068] Step 102: According to the formula Determine offset Δ for PUCCH power control calculation PUCCH_TF,c (i), where g(O UCI / N RE ) for O UCI and N RE is a function of variable .

[0069] Among them, O UCI May mean that the UCI includes the number of bits including the CRC.

[0070] In a possible implementation,...

example 1

[0091] Suppose it is PUCCH format 2 in advance, 18≤O UCI ≤25, and use frequency hopping to set a=2.2902, b=0.1479, that is, set a1=2.2902, b1=0.1479 in Table 1, then:

[0092] Get O in UE UCI =18, and calculate N through the parameters set by the upper layer RE =16, according to the formula Δ can be calculated PUCCH_TF,c (i)=7.4887, that is, the power control offset suitable for the Polar code is obtained.

[0093] see image 3 , it can be seen that the different O UCI / N RE The corresponding g(O UCI / N RE ) function values ​​are relatively close to the set sample data.

example 2

[0095] Suppose it is PUCCH format 2 in advance, 18≤O UCI ≤25, and frequency hopping is not used. Set a=2.1871, b=0.4385, that is, set a2=2.1871, b2=0.4385 in Table 1, then:

[0096] Get O in UE UCI =20, and calculate N through the parameters set by the upper layer RE =16, according to the formula Δ can be calculated PUCCH_TF,c (i)=9.1727, that is, the power control offset suitable for the Polar code is obtained.

[0097] see Figure 4 , it can be seen that the different O UCI / N RE The corresponding g(O UCI / N RE ) function values ​​are relatively close to the set sample data.

Abstract

The embodiment of the invention provides a PUCCH (Physical Uplink Control Channel) power control offset determination method and device, which are used for solving the technical problem that the existing PUCCH power control offset determination method cannot adapt to a new wireless communication system. The method comprises the following steps: determining the bit number OUCI of first uplink control information UCI needing to be transmitted on a PUCCH, and determining the number NRE of resource elements RE bearing the first UCI in the PUCCH; determining the offset delta PUCCH _ TF, c (i) for PUCCH power control calculation according to a formula, wherein g (OUCI / NRE) is a function with OUCI and NRE as variables.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for determining a power control offset of a Physical Uplink Control Channel (PUCCH). Background technique [0002] With the development and change of mobile communication service requirements, organizations such as the International Telecommunication Union (ITU) and the 3rd Generation Partnership Project (3GPP) have begun to study new wireless communication systems, such as the fifth generation wireless communication System (5Generation New RAT, 5G NR). [0003] During the discussion of NR, it is assumed that the power control of PUCCH in slot (slot) i on carrier c is performed by the following formula (1): [0004] [0005] Among them, P 0_PUCCH,c (b) The PUCCH target power configured for the upper layer of the carrier c is obtained by combining the cell-specific part and the user terminal (User Equipment, UE)-specific part; [0006] PL...
