Abstract

The present application discloses a time slot type indication method, determination method and device, including: a network device generates first indication information, wherein the first indication information indicates the time slot type of the first time slot, when the first time slot When the time slot type of a time slot is a predefined type, the first indication information is also used to indicate whether the second time slot is a full uplink time slot, and the first time slot is a time slot including a downlink control channel; The network device sends the first indication information through a downlink control channel of the first time slot.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a time slot type indication method, determination 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 slots. The base station needs to dynamically notify the ...
