1. A method comprising:

  • transmitting a communication signal over each of one or more spatial division multiple access (SDMA) channels of a multi-access channel to one or more corresponding user terminals; and

    determining a set of transmit spatial weights for a synchronization burst corresponding to one of one or more user terminals attempting to reestablish communication over an SDMA channel of the multi-access channel, the set of transmit spatial weights determined such that interference caused by one or more communication signals to the synchronization burst is reduced.
