Abstract

A resource indication method and device are used for improving the success rate of receiving data by a terminal. The method comprises the following steps: 1, preparing raw materials; the terminal receives first indication information from the base station, wherein the first indication information is used for indicating resource configuration of downlink data transmission, the resource configuration comprises an aggregation level of a time scheduling unit and a time domain position in a single time scheduling unit, and the aggregation level represents the number of the time scheduling units contained in the downlink data transmission resource; the terminal determines that time domain resources within the single time scheduling unit are valid for each time scheduling unit in the aggregationlevel and receives the downlink data transmission therefrom.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a resource indication method and device. Background technique [0002] Please refer to figure 1 , in the Long Term Evolution (LTE) system, the Physical Downlink Control Channel (PDCCH) occupies the entire bandwidth in the frequency domain, and may occupy the first 1~1 of a subframe in the time domain. There are 4 symbols, and a physical downlink sharing channel (Physical Downlink Sharing Channel, PDSCH) occupies the next symbol after the PDCCH in the time domain. in, figure 1 The subframe is used as the scheduling unit. [0003] It can be seen that in the LTE system, the terminal can know the position of the start symbol of the PDSCH according to the number of symbols occupied by the PDCCH indicated in the Physical Control Format Indicator Channel (PCFICH), and the end symbol of the PDSCH defaults to the subframe the last symbol of . ...
