Embodiment 1

[0128] This embodiment 1 is applicable to the situation of position relationship 1, resource blocks of physical uplink control channel format 3 are placed continuously, and the effective channel index of physical uplink control channel format 3 Start from 0.

[0129] Such as Figure 6As shown, the position of the physical uplink control channel format 3 in the total physical uplink control channel area can be the above-mentioned positional relationship 1: from the bandwidth edge to the bandwidth center, followed by the physical uplink control channel format 3 area, the physical uplink control channel area, and the physical uplink control channel area. Channel format 2 / 2a / 2b area, mixed resource block (if configured) and physical uplink control channel format 1 / 1a / 1b area.

[0130] At the same time, it is assumed that the physical uplink control channel format 3 adopts the frame structure of the conventional cyclic prefix, and the data-reference signal structure is a structur...

Embodiment 2

[0157] The second embodiment is applicable to the situation of the positional relationship 2, and the resource blocks of the physical uplink control channel format 3 are placed continuously.

[0158] As shown in Figure 7, the position of the physical uplink control channel format 3 in the total physical uplink control channel area can be the above-mentioned positional relationship 2: from the edge of the bandwidth to the center of the bandwidth, followed by the physical uplink control channel format 2 / 2a / 2b area, Physical Uplink Control Channel Format 3 area, Hybrid Resource Block (if configured) and Physical Uplink Control Channel Format 1 / 1a / 1b area.

[0159] At the same time, it is assumed that the physical uplink control channel format 3 adopts the frame structure of the conventional cyclic prefix, and the data-reference signal structure is a structure containing two reference signals in one time slot, and the reference signal does not use time domain extension, and does n...

Embodiment 2-1

[0161] In this embodiment, the resource blocks of the physical uplink control channel format 3 are placed continuously, and the configuration And it represents the number of PRBs occupied by PUCCH format 3, A small index is mapped to an RB at the edge of the bandwidth, and the effective channel index Start from 0.

[0162] Such as Figure 7-1 As shown, under this positional relationship, the base station configures the following relevant parameters for the terminal for the terminal to perform channelization of the physical uplink control channel format 3:

[0163] Indicates the total number of physical resource blocks occupied by physical uplink control channel format 2 / 2a / 2b and physical uplink control channel format 3, assuming here

[0164] Indicates the cyclic shift interval of the CG-CAZAC sequence, its value is 1, 2, 3, here it is assumed

[0165] Indicates the channel index obtained by the terminal for sending the physical uplink control channel format ...

Abstract

A method and system for determining physical uplink control channel resources are disclosed in the present document, a terminal determines a frequency domain resource, namely a location of a physical uplink control channel format 3 in total physical uplink control channel areas, used when the physical uplink control channel format 3 is sent according to parameters configured by a base station, and the location is determined according to a set location relationship. One location relationship is: from a bandwidth edge to a bandwidth center, the total physical uplink control channel areas including in turn a physical uplink control channel format 3 area, a physical uplink control channel format 2 / 2a / 2b area, a hybrid resource block and a physical uplink control channel format 1 / 1a / 1b area. In the present document, a feasible scheme is provided for determining resources of the physical uplink control channel format 3, which improves the system performance.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and a system for determining physical uplink control channel resources in a large bandwidth system. Background technique [0002] It is stipulated in the Long Term Evolution (LTE for short) system that when there is no uplink data to be sent, the physical uplink control channel is sent on a fixed time-frequency resource. Such as figure 1 As shown, a physical uplink control channel occupies one resource block in the frequency domain (one resource block occupies 12 subcarriers), and lasts for two time slots in the time domain, that is, one subframe (1ms). The number of symbols included varies depending on the cyclic prefix used by the frame. In addition, the control channel is frequency hopped over two time slots to obtain frequency domain diversity gain. The physical uplink control channel of each user equipment (User Equipment, UE for short) in the cell is code division mult...
