Problems solved by technology

[0007] Therefore, when the terminal device adopts the packet-based ACK / NACK feedback method, if it receives DCI format 1_0, it cannot generate uplink feedback information according to the normal packet-based ACK / NACK feedback method due to the lack of necessary information in DCI format 1_0. This leads to problems such as low uplink transmission efficiency and large service delay, resulting in limited scheduling and loss of system efficiency

Abstract

The invention discloses an uplink information generation method and a device thereof. The method comprises the following steps: receiving at least one first signaling, wherein a physical channel scheduled by the first signaling or a physical channel bearing the first signaling has no group information; determining a first transmission resource for transmitting first feedback information corresponding to the first signaling; and the terminal device generating a first feedback information codebook, wherein the first feedback information codebook comprises the first feedback information and second feedback information, the second feedback information being feedback information corresponding to a target group indicated by a second signaling, and a transmission resource of the second feedback information being overlapped with the first transmission resource. According to the method and the device, the normal data transmission function can be ensured to be maintained when the terminal equipment and the network equipment must use the ungrouped information in a packet-based feedback mode on the premise of not modifying the ungrouped information.

Description

[0001] This application is a divisional application of an application with an application date of September 30, 2019, an application number of 2019800690008, and an invention title of "a method and device for generating uplink information". 【Technical field】 [0002] The present invention relates to the technical field of communications, in particular to the technical field of uplink information transmission. 【Background technique】 [0003] The unlicensed spectrum is the spectrum allocated by the country and region that can be used for radio equipment communication. This spectrum is usually considered a shared spectrum, that is, communication equipment in different communication systems can be used as long as they meet the regulatory requirements set by the country or region on this spectrum. To use this spectrum, there is no need to apply to the government for exclusive spectrum authorization. With the development of wireless communication technology, both LTE (Long Term Ev...
