Embodiment Construction

[0044] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0045] In 3GPP, the ePDCCH channel is introduced to enhance the performance of PDCCH, and at the same time, a new transmission PDCCH area is introduced. In this embodiment, a method for obtaining the PUCCH channel resource for transmitting ACK / NACK corresponding to the PDSCH of ePDCCH is provided. This method ensures The HARQ process corresponding to ePDCCH is carried out normally, and the compatibility between the LTE-Advanced system and the LTE Release-8 system is guaranteed, so that the LTE-Advanced terminal can obtain the maximum frequency selective gain. It should be noted that the following embodiments and their preferred implementations The system to which the method is applied is not limited ...

Abstract

The invention discloses a resource determination method and a device for a physical uplink control channel (PUCCH) of a large-band-width system. The method comprises the following steps that: user equipment obtains the channel resource index of the PUCCH, wherein the PUCCH is used for carrying the affirmative check/negative check (ACK/NACK) information of a physical downlink share channel (PDSCH) indicated with an enhanced physical uplink control channel (ePUCCH); and the user equipment determines the resources used by the PDSCH according to the obtained channel resource index. Through the method and the device provided by the invention, the normal proceeding of a hybrid automatic repeat request (HARQ) process corresponding to the ePDCCH is ensured.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for determining physical uplink control channel resources of a large bandwidth system. Background technique [0002] figure 1 It is a schematic diagram of the frame structure according to the LTE (Long Term Evolution, long-term evolution) system FDD (Frequency Division Duplex, frequency division duplex) mode in the related art, as figure 1 As shown, in the frame structure of FDD mode, a 10ms radio frame (wireless frame) is composed of twenty slots (time slots) with a length of 0.5ms and numbers 0 to 19. The length of time slots 2i and 2i+1 is 1ms subframe (subframe) i. figure 2 It is a schematic diagram of the frame structure according to the LTE (Long Term Evolution, long-term evolution) system TDD (Time Division Duplex, time division duplex) mode in the related art, as figure 2 As shown, in the frame structure of the TDD mode, a 10ms radio frame (wirel...
