Embodiment Construction

[0159] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0160] refer to Figure 4 As shown, in the embodiment of the present invention, the detailed process of transmitting uplink control information is as follows:

[0161] Step 400: The terminal determines resources for transmitting uplink control information, where the resources include resources occupied in the time domain and resources occupied in the frequency domain, wherein the duration of the resources occupied in the time domain is less than 1 ms.

[0162] Step 410: the terminal transmits uplink control information on the determined resource.

[0163] Specifically, in step 400, the core idea of ​​this embodiment is:

[0164] Among the resources determined by the terminal for transmitting uplink control information, the size of resources occupied in the frequency domain is represented by the number of subcarriers (Sub Carrier...

Abstract

The invention relates to the field of the communication, and in particular relates to a transmission method and device of uplink control information. The method comprises the following steps: a terminal determines a resource for transmitting the uplink control information, the resource comprises the time domain occupied resource and the frequency domain occupied resource, wherein the time length of the time domain occupied resource is less than 1ms; and then the terminal transmits the uplink control information on the determined resource. Therefore, a transmission solution scheme of the uplink control information is provided aiming at the shortened TTI condition, the normal feedback of the uplink control information is supported, and the system performance is guaranteed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for transmitting uplink control information. Background technique [0002] With the development and change of mobile communication service requirements, international organizations have defined higher user plane delay performance requirements for future mobile communication systems. One of the main methods to reduce user delay performance is to reduce the length of Transmission Time Interval (Transmission Time Interval, TTI). [0003] refer to figure 1 As shown, in the frame structure used by the existing long term evolution (Long Term Evolution, LTE) frequency division duplex (Frequency Division Duplex, FDD) system, different carrier frequencies are used for uplink and downlink transmission, and the same frequency is used for uplink and downlink transmission. frame structure. On each carrier, a 10ms long radio frame contains 10 1ms subframes, and each sub...
