Problems solved by technology

[0005] However, since the HS-SCCH signaling lengths supporting the MIMO function and the CPC function are not the same, in order to prevent the UE from performing blind detection or blind decoding on the HS-SCCH, the HS-SCCH transmission mode provided in the prior art can only Support one of the MIMO function or CPC function, that is, provide the corresponding HS-SCCH transmission mode for single-stream control information bearing and dual-stream control information bearing in MIMO, or provide the corresponding HS-SCCH transmission mode for CPC semi-persistent Resource control information bearing or CPC temporary scheduling resource control information bearing, but not compatible with MIMO function and CPC function

Abstract

The invention provides a method, a base station and a terminal for transmitting and receiving a shared control channel of a high-speed downlink shared channel (HS-SCCH) and sets HS-SCCH signalling adopting the same length under the conditions of each functional requirement. The method comprises the following steps that: the base station determines channelized code information corresponding to the current functional requirement according to the corresponding relationship between preset channelized code information and the functional requirement, and transmits the HS-SCCH signalling containing the determined channelized code information to the terminal, wherein the functional requirement comprises a multiple-input-multiple-output (MIMO) function or a continuous packet connectivity (CPC) function. The invention can be compatible with the MIMO function and the CPC function and avoid blind test or a blind decoding on the HS-SCCH by the terminal.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method, base station and terminal for sending and receiving a shared control channel (HS-SCCH) of a high-speed downlink shared channel. Background technique [0002] In High Speed ​​Packet Access (HSPA, High Speed ​​Package Access) technology, the base station needs to pass the shared control channel ( HS-SCCH) to send the HS-PDSCH control information assigned to the UE to the UE. Among them, the HS-SCCH signaling carried by the HS-SCCH includes: channelization code set identification, time slot (TS) information, modulation mode (Mod) information, data block size (TBS) information, hybrid automatic repeat request (HARQ) Information, HS-SCCH cyclic sequence identification (HCSN) and UE identification, etc., wherein, the channelization code set identification includes: the start code and stop code that identify the start code channel information and end code channel inf...
