Information processing method, terminal device, network device and communication system

Abstract

The invention provides an information processing method, a terminal device, a network device and a communication system. The method includes: respectively encoding uplink control information UCI and data to obtain coded bits of the UCI and coded bits of the data; multiplexing the coded bits of the UCI and the coded bits of the data to obtain a multiplex Using a bit stream; carrying the multiplexed bit stream on the physical uplink shared channel PUSCH and sending it to the network device, the length of the transmission time interval TTI of the UCI is less than or equal to 0.5 milliseconds, which can effectively reduce the data transmission delay, thereby Meet the needs of low-latency services.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to an information processing method, terminal equipment, network equipment, and a communication system. Background technique [0002] Long Term Evolution (LTE) is the long-term evolution of the Universal Mobile Telecommunications System (UMTS) technical standard formulated by The 3rd Generation Partnership Project (3GPP). has a wide range of applications. [0003] In the existing LTE system, a transmission time interval (Transmission Time Interval, referred to as TTI) transmission mechanism based on 1 subframe, wherein the duration of a subframe is 1 millisecond, and each subframe is divided into two slots (slot) , the length of each slot is 0.5 milliseconds, and each slot consists of 6 or 7 symbols. When uplink control information (Uplink Control Information, referred to as UCI) is carried on a physical uplink shared channel (Physical Uplink Shared Channel,...

Problems solved by technology

[0006] In the first aspect, the embodiment of the present invention provides an information processing method, which is described from the perspective of terminal equipment, and the method includes encoding the CUI and data separately, and multiplexing the encoded bits obtained by the UCI and the encoded bits of the data , to obtain the multiplexed bit stream; the multiplexed bit stream is carried on the PUSCH and sent to the network device. Since the length of the TTI of UCI is less than or equal to 0.5 milliseconds, the processing method of this information solves the problem that the prior art cannot support UCI less than 1 ms Transmission problems can effectively reduce data transmission delay, so as to meet the needs of low-latency business
