Embodiment Construction

[0093] The core idea of ​​the present invention is: in order to further improve the transmission rate of the downlink data in the TDD HSDPA system, the 64QAM modulation mode is introduced, and like this, the modulation mode that HS-PDSCH can use just becomes three kinds, and the HS in the existing specification - The modulation mode signaling in the SCCH signaling has only 1 bit, and cannot indicate three modulation modes. The present invention allows the HS-PDSCH code channel allocation indication start code k by expanding the assignment range of the signaling code indicated by the HS-PDSCH code channel allocation indication in the HS-SCCH start greater than the termination code k stop , so that without changing the signaling lengths of the HS-SCCH in the existing specifications, the method of indicating the three downlink modulation modes and code channel allocation is reasonably designed, and the system's determination of the adjustment mode is minimized through a simple ma...

Abstract

The invention discloses a indication method for high speed downlink shared physical channel modulation mode, relates to indication technology of channel modulation mode, and aims to solve the current problem that HSDPA system can not display 64QAM modulation mode. The adopted technical solution comprises: expanding HS-PDSCH code track distribution indication signaling in shared control channel HS-SCCH, and indicating HS-PDSCH modulation mode together with the modulation mode signaling. The invention further discloses a determining method for high speed downlink shared physical channel modulation mode, and a high speed downlink shared physical channel modulation mode indicating and determining apparatus for realizing the above method. The invention designs out a method for indicating three downlink modulation mode and code track distribution, without changing the length of each signaling of HS-SCCH in existing standard, and minimizes the complexity of system to determine adjustment mode through simple mapping relation.

Description

technical field [0001] The present invention relates to the indication and determination technology of the channel modulation mode, more precisely, relates to the indication method and device of the modulation mode of High Speed ​​Physical Downlink Shared Channel (HS-PDSCH, High Speed ​​Physical Downlink Shared Channel) and the determination of the HS-PDSCH modulation mode Methods and devices. Background technique [0002] With the increasing demand for high-speed data services in the market, 3GPP introduced five important enhancement technologies in the Release5 and Release6 version specifications: High Speed ​​Downlink Packet Access (HSDPA, High Speed ​​Downlink Packet Access) technology to match other wireless access technologies contend. The HSDPA technology is an improved technology introduced in the 3G system in order to increase the downlink service rate of the system. HSDPA is a collection of some wireless enhancement technologies. Its purpose is to meet the asymme...
