ABSTRACT:
Techniques for selecting transmit formats in a manner to account for the degrees of resource reuse for multiple data streams sent simultaneously from multiple antennas are described. The degree of resource reuse for each data stream indicates the amount of reuse of resources (e.g., orthogonal codes or subcarriers) observed by that stream. Interference estimates for the multiple data streams are derived based on an initial resource assignment. The degrees of resource reuse are determined based on the interference estimates and are used to derive at least one correction factor. At least one transmit format is then selected for the data streams using the at least one correction factor. Each data stream is associated with a transmit format that indicates the amount of resources to use for the data stream and other parameters. Resources are assigned to each data stream in accordance with its transmit format.
