Abstract

The invention relates to a discontinuous transmission method for user terminal detection and a user terminal in a TD-SCDMA (Division-Synchronization Code Division Multiple Access) system. The method comprises the following steps that: a downlink control module receives a TFCI (Transport Format Combination Indicator) value sent by a downlink transmission business receiver module; the downlink control module judges whether the TFCI value is 0 or an effective value; if the TFCI value is 0 or an effective value, the SIR (Signal to Interference Ratio) value of a business time slot, which is calculated and sent by a joint detection module, is received; and the downlink control module determines to detect the state of the current discontinuous transmission (DTX) of the terminal according to the TFCI value and the SIR value. In the method and the user terminal, the SIR value detection and the TFCI value detection are combined to determine the DTX state so as to more truly reflect the signal quality of the current UE and improve the accuracy of the DTX detection. The user terminal has the advantages of simple structure, lower complexity and stable performance and is easy to realize.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for a user terminal to detect the working state of downlink discontinuous transmission (DTX) in a TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access) system and the user terminal. Background technique [0002] In the TD-SCDMA communication system's Uu interface physical layer technical requirements standard "3GPP TS 25.224Physical layer procedures (physical layer procedures)", in the physical channel S-CCPCH (auxiliary common control physical channel), UL DPCH (uplink dedicated physical Channel), DL DPCH (Downlink Dedicated Physical Channel), PUSCH (Physical Uplink Shared Channel) and PDSCH (Physical Downlink Shared Channel) can apply DTX (Discontinuous Transmission, discontinuous transmission). [0003] After the wireless link is established, when there is no data to send in the uplink (forward link) or downlink (reverse link), the physical ...
