Embodiment Construction

[0111] The embodiment of the present application may be applicable to a 4G (fourth generation mobile communication system) evolution system, such as an LTE (Long Term Evolution, Long Term Evolution) system, or may also be a 5G (fifth generation mobile communication system) system, such as a new wireless interface Access network of new radio access technology (New RAT); CRAN (Cloud Radio Access Network, cloud radio access network) and other communication systems. The communication system includes terminal equipment and network equipment.

[0112] Hereinafter, some terms used in this application are explained to facilitate the understanding of those skilled in the art.

[0113] 1) Terminal equipment, also called User Equipment (UE), is a device that provides voice and / or data connectivity to users, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and the like. Common terminals include, for example, mobile phones, tablet computers, no...

Abstract

The present application discloses a method and device for indicating control information, and a method and device for confirming control information. The method for indicating the control information includes: the network device generates first indication information, where the first indication information is used to indicate the slot type of the first time slot and the symbol of the downlink control channel in the first time slot number, the first time slot is the time slot where the first indication information is located, and the first indication information is also used to indicate whether the second time slot is a full uplink time slot; the network device passes the The downlink control channel sends the first indication information.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a time slot type indication method and device. Background technique [0002] In the future fifth-generation mobile communication system (The 5th Generation, 5G), there are four possible types of slots, namely the main uplink (Uplink-dominant, UL-dominant) slot, the full uplink (UL-dominant) only) slot, main downlink (DL-dominant) slot and full downlink (DL-only) slot. Among them, the UL-dominant slot, the DL-dominant slot and the DL-only slot all include the downlink control channel, and only the UL-only slot does not include the downlink control channel. [0003] The 5G system introduces a dynamic time division duplexing (Time Division Duplexing, TDD) mechanism. Under this mechanism, the uplink and downlink subframe ratios of the system change dynamically at the granularity of time slots. The base station needs to dynamically notify the terminal of the typ...
