Problems solved by technology

[0016] However, when the UE applies HARQ-ACK multiplexing or schedules multiple PDCCHs at the same time, it is possible to lose the PDCCH, resulting in a wrong PDCCH start index, resulting in collision of PUCCH resources of different UEs

Embodiment 1

[0080] The UE determines PUCCH resource index according to its C-RNTI.

[0081] Specifically, (1) is calculated according to the formula PUCCH resource index:

[0082] r = Mod (C-RNTI UE , M) Equation (1)

[0083] Where, r PUCCH resource index for the PUCCH centralized resource subspace, C-RNTI UE The UE's C-RNTI, PUCCH resources M is the number of resource subsets.

[0084] In Table 4, the C-RNTI of the UE is calculated through Equation (1) is obtained 0 / 1, when set to 0, the corresponding index of the PUCCH resource subset PUCCH 0; and when taking a corresponding subset index PUCCH PUCCH resources 1.

[0085] Table 4

[0086] C-RNTI of the UE Ari PUCCH resource set 0 0 {1 st ,5 th },{2 nd ,6 th },{3 rd ,7 th },{4 th ,8 th }

Embodiment 2

[0088] The UE determines PUCCH resource index according to its own C-RNTI and the current slot index.

[0089] Specifically, (2) is calculated according to the formula PUCCH resource index:

[0090] r = Mod (n, M) Equation (2)

[0091] Wherein, M being the number of PUCCH resource sub-set, r is a PUCCH resource index for the PUCCH focused subset of resources.

[0092] in, And c (i) is a pseudo-random sequence initialized as c init = N C-RNTI , N C-RNTI It is C-RNTI UE, n is slot Time slot index, X is a constant, in the range {1,2 ... 9};

[0093] Alternatively, n = n slot + N c-RNTI , N C-RNTI It is C-RNTI UE, n is slot The time slot index.

Embodiment 3

[0095] The UE determines PUCCH resource index according to its own C-RNTI and a current radio frame number (slot and index).

[0096] Specifically, (3) is calculated according to the formula PUCCH resource index:

[0097] r = Mod (n, M) Equation (3)

[0098] Wherein, M being the number of PUCCH resource sub-set, r is a PUCCH resource index for the PUCCH focused subset of resources.

[0099] in, And c (i) is a pseudo-random sequence initialized as c init = N C-RNTI , N C-RNTI It is C-RNTI UE, n is frame A radio frame number, n slot Time slot index, Y is a constant, in the range {1,2 ... 9}, X is a constant, in the range {0,1,2, ... 9};

[0100] Alternatively, n = n frame + N c-RNTI , N C-RNTI It is C-RNTI UE, n is frame A radio frame number.

[0101] Embodiment of the present invention further provides an apparatus for determining PUCCH resources, the UE is located in the apparatus, such as image 3 As shown, the apparatus comprises:

[0102] A first obtaining unit 11, configured t...

Abstract

The present invention provides a method, device and user equipment for determining PUCCH resources. The method includes: obtaining the cell wireless network temporary identifier C-RNTI of the UE and the number of resources in the physical uplink control channel PUCCH resource subset; determining the PUCCH according to the UE's C-RNTI and the number of resources in the PUCCH resource subset PUCCH resource index in the resource subset. The present invention can avoid PUCCH resource conflict among different UEs caused by PDCCH loss.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology, and more particularly to a method, apparatus, and user equipment for determining a PUCCH resource. Background technique [0002] 3GPP (3rd Generation Partnership Project, third-generation partner plan) NR (Newradio, new air) system frame structure diagram figure 1 As shown, within a wireless frame having a time domain length of 10 ms, each wireless frame is divided into a subframe having a length of 1 ms of the same size of 1 ms, and is different from the subframe, each subframe, can contain multiple time slots. Each time slot is composed of a certain number of symbols, and the symbols are determined by the CP (Cyclic Prefix, the cyclic prefix) type. [0003] Purch (Physical Uplink Control Channel, Physical Uplink Control Channel) is a physical channel of the uplink in the NR system, where uplink control information is carried. The purpose of setting the PUCCH is that when the ...
