Abstract

The invention discloses a DTX detection method, device and base station. The DTX detection method includes the steps of: extracting information bits used for performing DTX detection from a feedback signal sent by an uplink terminal, and processing the extracted information bits according to different polarities; obtaining a DTX detection value according to information bits of different polarities; and comparing the DTX detection value with a preset DTX detection threshold value, and determining whether the uplink terminal is in a DTX state according to a comparison result. The scheme provided by the invention utilizes polarity characteristics of information bits to complete DTX detection, can greatly reduce possibilities of false detection and missing detection, and improves the precision of DTX detection, particularly under the condition of a small TBSize.

Description

technical field [0001] The present invention relates to the communication field, in particular to a DTX (Discontinuous Transmission, discontinuous transmission) transmission detection method, device and base station. Background technique [0002] The 3GPPTS36.212 protocol defines that the uplink control information UCI can be transmitted on the physical uplink control channel PUCCH (PhysicalUplinkControlCHannel, physical uplink control channel) or on the PUSCH (PhysicalUplinkSharedChannel, physical uplink service shared channel), and the transmission mode includes the bonding mode and multiplexing modes. For example, see figure 1 The shown UL-SCH (Uplink Shared Channel, uplink shared channel) and control information transmit resource mapping diagrams on the PUSCH. In order to prevent the loss of data packets, the HARQ (HybridAutomaticRepeatRequest, hybrid automatic retransmission) retransmission mechanism is defined in the protocol. There is a certain interval between the ...
