Problems solved by technology

During the inactive time of the DRX cycle, in order to save power, the UE usually does not receive DCI format 2_0, which makes the UE unable to obtain the latest DCI format 2_0, which ultimately affects signaling and data transmission

Embodiment Construction

[0032] In actual communication, the base station will indicate some flexible time slots (Flexible) to the UE through RRC signaling or system messages in advance. For example, which time slots in a radio frame (10ms) are variable time slots, or which symbols (Symbol) in which time slots are variable, and then the base station notifies the UE whether these variable time slots are downlink or uplink through DCI format 2_0 , or which symbols in the slot are downlink or which symbols are uplink.

[0033] In a variable time slot, if the UE is previously configured by the high layer to receive PDSCH, but if the UE does not receive DCI format 2_0, the UE does not need to receive PDSCH data in this time slot (that is, the downlink data transmitted through PDSCH ). In a variable time slot, if the UE is configured by the base station to detect DCI, only when the UE receives DCI format 2_0 and the DCI indicates that the variable time slot is downlink, the UE needs to detect the correspon...

Abstract

A DCI detection method, a user terminal and a computer-readable storage medium. The method includes: judging whether it is necessary to detect the DCI of the time slot format information within the inactive time of the current DRX cycle; The cycle duration is the detection time slot of the DCI of the latest time slot format information; the detection of the DCI of the time slot format information is performed according to the determined detection time slot, and the latest time slot format information is obtained. By applying the above solution, the power consumption of the UE can be reduced while obtaining the latest time slot format information.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a DCI detection method, a user terminal and a computer-readable storage medium. Background technique [0002] In the fifth generation mobile communication technology (5G) (or called New Radio access technology, NR), a base station schedules a user terminal (User Equipment, UE) through downlink control signaling (Downlink Control Information, DCI). [0003] Specifically, the DCI may indicate an uplink grant (UL Grant) or a downlink assignment (DL Assignment). Wherein, according to the uplink authorization, the UE sends data to the base station according to the allocated transmission resource in the designated time slot. The downlink assignment is used to indicate to the user terminal the data transmitted on the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH). At this time, the DCI needs to indicate the modulation and coding format fo...
