Abstract

The invention discloses HS-SCCH signaling and HS-SICH signaling supporting MIMO HSDPA, and an encoding method thereof, which are used for supporting the HS-DSCH transmission of a PARC MIMO system. Theinvention adopts the technical scheme that: the HS-SCCH signaling comprises the following information bits: 8 bits of first antenna spreading code set information, 8 bits of second antenna spreadingcode set information, 5 bits of first antenna time slot information, 5 bits of second antenna time slot information, 1 or 2 bits of first antenna modulation mode information, 1 or 2 bits of second antenna modulation mode information, 6 or 5 bits of transmission block size information, m bits of data ratio of two antennas, 3 bits of hybrid automatic retransmission request process information, 3 bits of redundant version information, 1 bit of new data indicating information, 3 bits of HS-SCCH cyclic sequence number, and 16 bits of UE identification number. The HS-SCCH signaling and the HS-SICH signaling supporting the MIMO HSDPA, and the encoding method thereof are applied in the field of mobile communication.

Description

technical field [0001] The invention relates to signaling transmission in a 3G wireless communication system, in particular to signaling supporting MIMO HSDPA in a TDD system and a coding method thereof. 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 introduci...
