SPATIAL MULTIPLEXING IN A CELLULAR NETWORK |
摘要 |
The present invention provides methods and apparatus for implementing spatial multiplexing in conjunction with the one or more multiple access protocols during the broadcast of information in a wireless network. One example includes transmitting a first and a second data signal to a remote unit from a respective first and a second spatially separate antenna of a base station so that the first and second data signals have a first spatial configuration, determining that the first and the second data signals are not spatially separated by the remote unit, reconfiguring the (spatial multiplexing logic 104) spatial configuration of the first and second data signals to a second spatial configuration, and transmitting a third and fourth data signal to the remote unit from a second different antenna configuration according to the second spatial configuration. |
