Embodiment Construction

[0092] In the prior art, taking the LTE communication system as an example, the physical layer control signaling (also known as layer-1 control signaling) is expressed as Downlink Control Information (DCI), and the DCI is transmitted through the Physical Uplink Control Channel (Physical Downlink Control Channel, PDCCH) to transmit. The user equipment obtains the physical layer control signaling sent by the base station to the user equipment, such as scheduling information, by blindly detecting the PDCCH. Media access layer (MAC) control signaling (also known as layer 2 control signaling) is represented as a MAC control entity (Control Entity, CE), and the MAC CE is carried in the header of a MAC protocol data unit (Protocol Data Unit, PDU) ( Header). The control signaling of the radio resource control layer (also known as layer 3 control signaling) is expressed as radio resource control signaling (Radio Resource Control, RRC), and the RRC is finally mapped to the physical dow...

Abstract

The invention discloses user equipment, network side equipment and a control method for the user equipment. The method comprises the following steps of generating uplink and downlink control information of the user equipment; adding the generated uplink and downlink control information into a downlink control signal; and sending the downlink control signal to the user equipment in order to indicate the user equipment to configure corresponding parameters according to the uplink and downlink control information to carry out data transmission with a network side. According to the scheme, the flexibility of configuration of the user equipment can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a user equipment, a network side equipment and a control method for the user equipment. Background technique [0002] The fifth generation of mobile communication technology (5G) is the main direction of the development of the new generation of mobile communication technology and an important part of the future new generation of information infrastructure. Compared with 4G, 5G will not only further enhance the user's network experience, but also meet the application requirements of the Internet of Everything in the future. From the perspective of user experience, 5G has higher speed and wider bandwidth. It is estimated that the speed of 5G network will be about 10 times higher than that of 4G. Higher network experience requirements such as high-definition video. From the perspective of industry applications, 5G has higher reliability and lower latency, which can ...
