Abstract

The embodiment of the invention discloses an E-HICH (E-DCH hybrid automatic repeat request indicator channel) joint detection method, comprising the following steps: carrying out joint detection on received signals of a sub-frame to which the E-HICH attributes to obtain the estimation of the symbol sequence of the sub-frame, wherein the symbol sequence is transmitted in the E-HICH; demodulating the estimation of the obtained symbol sequence, and deleting an idle bit to obtain a demodulated bit sequence; and determining the control information transmitted to UE (user equipment) in the E-HICH according to the demodulated bit sequence and a signature sequence which corresponds to the UE and is used for transmitting the control information. By using the E-HICH joint detection method, the control information which is transmitted to the confirmed UE can be extracted from the signals transmitted in the E-HICH.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a joint detection method and device for E-HICH (E-DCH Hybrid ARQ Indicator Channel: Enhanced Dedicated Channel Hybrid Automatic Repeat Request Indicator Channel). Background technique [0002] In order to meet the needs of high-speed data services in mobile networks, Time Division Synchronous Code Division Multiple Access (TD-SCDMA, Time Division Synchronous Code Division Multiple Access) system introduces High Speed ​​Uplink Packet Access (HSUPA, High Speed ​​Uplink Packet Access) technology. The technology can greatly improve the uplink throughput and uplink peak rate. In HSUPA technology, a downlink physical channel called E-HICH is introduced. [0003] For a user terminal (UE) with a scheduled enhanced dedicated channel physical uplink channel (E-PUCH, E-DCH Physical Uplink Channel), when the UE schedules an enhanced dedicated channel (E-DCH) data block by schedulin...
