Problems solved by technology

[0003] In NR unlicensed (unlicensed), due to channel uncertainty, it is impossible to predict whether the channel is idle in advance
After detecting that the channel is idle and obtaining the channel occupancy time, if the base station does not inform the user equipment of the structure of the downlink transmission and uplink transmission within the channel occupancy time, the user equipment needs to monitor the DCI information all the time, resulting in increased power consumption of the user equipment
In addition, if the user equipment does not know which time slots or symbols are available for uplink, the user equipment must send a scheduling request to the base station and then receive a scheduling permission from the base station before performing uplink transmission, resulting in increased uplink transmission delay

Embodiment Construction

[0064] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0065] See figure 1 , figure 1 is a schematic diagram of the architecture of a signaling indication system provided by an embodiment of the present application. The signaling indication system includes a user equipment and a base station. The user equipment may refer to a device that provides voice and / or data connections to users, or may be connected to to a computing device such as a laptop or desktop computer, or it may be a stand-alone device such as a Personal Digital Assistant (PDA). User equipment can also be called a system, a subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device. The base station can be an access point, Node B, evolved node (Enhanced Node Basestation, eNB) or 5G base station (Next generation Node Base station, gNB), w...

Abstract

The embodiment of the present application discloses a signaling indication method, including: detecting the channel; when detecting that the channel is in an idle state, determining the channel occupancy time; sending an indication signaling to the user equipment, and the indication signaling is used Indicates the time slot or symbol used for downlink transmission and the time slot or symbol used for uplink transmission within the channel occupation time. The embodiment of the present application also discloses a signaling indicating device and a storage medium. By adopting the embodiments of the present application, power consumption and time delay can be reduced.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to a signaling indication method, device and storage medium. Background technique [0002] In the new wireless technology (New Radio, NR), a time slot contains 14 symbols, and the time slot format includes three types: the first type, all 14 symbols are used for downlink transmission; the second type, all 14 symbols Used for uplink transmission; the third category, the 14 symbols include at least two of symbols used for downlink transmission, uncertain symbols, and symbols used for uplink transmission. In the NR licensed spectrum, the slot format supports radius configuration, which is given by Radio Resource Control (RRC) signaling. At the same time, dynamic configuration is also supported, which is explicitly given by the slot format indication (Slot FormatIndication, SFI) in the group common (group common) downlink control information (Downlink Control Informat...
