Patent ID: 8848735

Claim:
A method for Multiple Input Multiple Output, MIMO, transmission in a high speed packet access evolution system, comprising: determining, by a user equipment, signaling over a High Speed Shared Information Channel, HS-SICH according to a number of received data streams over a downlink service channel, and determining a channelization code resource over which the HS-SICH is borne according to the number of data streams over the downlink service channel, wherein if the received data stream over the downlink service channel is a single data stream, signaling of the single data stream is borne over the HS-SICH and a channelization code resource with a spread factor of 16 is allocated as the channelization code resource over which the HS-SICH is borne, wherein if the received data streams over the downlink service channel are dual data streams, signaling of the dual data streams is borne over the HS-SICH and a channelization code resource with a spread factor of 8 is allocated as the channelization code resource over which the HS-SICH is borne; encoding the signaling over the HS-SICH respectively; and multiplexing and mapping encoded signaling onto determined channelization code resource over which the HS-SICH is borne.
