Problems solved by technology

In all the remaining code channels, the orthogonality between the code channels is mainly used. Theoretically, the idle code channels carry the noise signal. The noise power can be estimated by using all the unscheduled idle code channels, so as to make the DTX decision, but Due to the difference in user transmit power and the time-varying nature of the wireless channel, it is very likely that some users will be falsely detected in a multi-user scenario.

Abstract

This specification provides a method for detecting discontinuous transmission of DTX, a device and a storage medium. The method includes: determining a user schedulable code channel, obtaining a power value of each user schedulable code channel, and according to the user schedulable code channel The power value of the channel is determined, the target code channel with the maximum power value is determined, the average noise power value of the non-user schedulable code channel adjacent to the target code channel is obtained, and the user schedulable code channel is determined according to the average noise power value. The power value for DTX detection.

Description

technical field [0001] The present disclosure relates to the field of wireless communications, and in particular, to a method for detecting discontinuous transmission of DTX, a device and a storage medium. Background technique [0002] PUCCH (Physical Uplink Control Channel, physical uplink control channel), used to carry UCI (Uplink Control Information, uplink control information) sent by the terminal, including CSI (Channel State Information, channel state information), HARQ (Hybrid Automatic Repeat Quest, mixed Automatic retransmission request) ACK (Acknowledgement, correct response) / NACK (Negative Acknowledgement, negative response) and SR (Schedule Request, scheduling request) information of the confirmation information. [0003] The DTX detection of PUCCH is to prevent the UE from not sending UCI information and the base station incorrectly detects it and brings "false alarms", thus causing problems such as user packet loss. Therefore, protocol 38.101 requires that the...
