Patent ID: 8270360

Claim:
A method for indicating a modulation mode in high speed downlink packet access, comprising the following steps: a NodeB receiving capability information reported by a terminal, when determining that the terminal supports 64QAM modulation mode, determining a transmission block size, a modulation mode and code channel resource to be indicated based on an capability constraint condition and the capability information, and when the determined modulation mode is the same as a basic modulation mode which is a minimum modulation mode satisfying requirement of the transmission block size, setting modulation mode information of a shared control channel for high speed downlink shared channel as 0 to indicate taking the basic modulation mode as the modulation mode of the terminal, when the determined modulation mode is one level higher than the basic modulation mode, setting the modulation mode information of the shared control channel for high speed downlink shared channel as 1 to indicate taking a modulation mode which is one level higher than the basic modulation mode as the modulation mode of the terminal, and then sending the shared control channel for high speed downlink shared channel to the terminal.
