Embodiment Construction

[0025] see figure 1 , which is a schematic diagram of a signal processing process of a high-speed shared control channel HS-SCCH disclosed in the present invention.

[0026] Step 110: combining HS-SCCH data and processing cyclic redundancy.

[0027] The HS-SCCH channel is used to carry the downlink control information related to high-speed downlink packet access to HSDPA. Each HS-SCCH channel only carries HS-DSCH-related downlink signaling for one UE at a time. The signaling information mainly includes: UE- Id, TFRI, HARQ related information, etc. TFRI mainly includes code time slot allocation information, modulation scheme information (QPSK / 16QAM) and transport block size. HARQ related information includes HARQ process information, redundancy version information and new data indication. The UE-Id information carries a corresponding UE ID number to indicate the UE for this data transmission.

[0028] Before channel coding is performed on the HS-SCCH data, some self-process...

Abstract

The disclosed signal process method for HS-SCCH comprises: after coding the HS-SCCH data, taking cancellation to match code rate, and finally forming a data block occupying a channel. This invention reduces channel occupied by every UE HS-SCCH control signal, decreases noise effect, and improves entire decoding performance.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a signal processing method and device for a high-speed shared control channel HS-SCCH. Background technique [0002] In the high-speed downlink packet intervention HSDPA, the high-speed shared data channel HS-DSCH is used for data transmission. Multiple UEs share the channel through time division multiplexing and code division multiplexing, and its physical channel is HS-PDSCH. In order to achieve fast control, HS-DSCH uses the high-speed shared control channel HS-SCCH as its dedicated downlink control channel to carry HSDPA-related downlink control information. Each HS-SCCH channel only carries HS-DSCH-related downlink for one UE at a time. Signaling, the signaling information mainly includes: UE-Id, TFRI, HARQ related information and so on. Therefore, for HSDPA, the terminal must obtain the corresponding control information on the HS-SCCH in order to receive the...
