Transmission structure supporting multi-user scheduling and MIMO transmission
First Claim
1. An apparatus comprising:
- at least one processor to assign multiple time segments of a transmission time interval (TTI) to at least one terminal, to map data for each terminal to at least one time segment assigned to the terminal, and to spread data in each of the multiple time segments with at least one channelization code used in the TTI; and
a memory coupled to the at least one processor.

Abstract
Techniques for transmitting data in a manner to support multi-user scheduling, multiple-input multiple-output (MIMO) transmission, and interference cancellation are described. A base station assigns multiple time segments of a transmission time interval (TTI) to at least one terminal, maps data for each terminal to at least one time segment assigned to the terminal, and spreads the data in each time segment with at least one channelization code used in the TTI. A terminal receives an assignment of at least one time segment from among multiple time segments of the TTI, obtains input samples for the at least one time segment, and despreads the input samples with the at least one channelization code used in the TTI.
