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 LTERelease-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 implementation modes The applied system is not limited to the LTE-Advanced...

Abstract

The present invention discloses a method and device for determining physical uplink control channel resources of a large-bandwidth system. The method includes: a user equipment acquires a channel resource index of a physical uplink control channel PUCCH, wherein the PUCCH is used to carry an enhanced physical downlink control channel ePDCCH indication Positive acknowledgment / negative acknowledgment ACK / NACK information of the physical downlink shared channel PDSCH; the user equipment determines resources used by the PDSCH according to the obtained channel resource index. The invention ensures that the HARQ process corresponding to the ePDCCH is carried out normally.

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 (LongTerm 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 (wirele...
