Abstract

The invention discloses HS-SCCH signaling and HS-SICH signaling of a TD-HSDPA MIMO system for avoiding a terminal carrying out blind detection for single-flow and double-flow HS-SCCH. The invention adopts the technical scheme that the transmission rate of the system can be effectively increased by introducing MIMO, the signaling comprises a single / double-flow identification information bit for identifying single flow and double flow, the lengths of the information bits of HS-SCCH of single-flow transmission and HS-SCCH of double-flow transmission are equal, and different modulation modes are indicated. The HS-SCCH signaling and the HS-SICH signaling of the TD-HSDPA MIMO system are applied in the field of mobile communication.

Description

technical field

[0001] The invention relates to signaling design, in particular to designing HS-SCCH signaling and HS-SICH signaling of a TD-HSDPA MIMO system. Background technique

[0002] With the continuous development of communication technology and the increasing requirements of users for service quality, the data transmission rate of up to 2Mbit / s defined by the 3rd Generation Partnership Project (3GPP) standard before Release 4 has gradually failed to meet the needs of users. The demand for high-speed data services. In this case, 3GPP introduced the High Speed ​​Downlink Packet Access (HSDPA) technology in the Release 5 specification.

[0003] HSDPA is an enhanced solution proposed by 3GPP Release 5, the main purpose is to support high-speed packet data services, and to obtain lower time delay, higher system throughput and stronger QoS guarantee. From a technical point of view, HSDPA enhances the air interface by introducing a high-speed downlink shared channel (HS-...
