Patent ID: 8107884

Claim:
A base station (BS) for use in a multi-input multi-output (MIMO) network, the MIMO network including another BS and a subordinated station (SS), the SS being within a signal coverage between the BS and the another BS, the another BS communicating with the SS by at least one first pilot structure in a first super frame, the BS comprising: a transceiver, being configured to receive the first super frame; a storage module, being configured to store pilot structure information; and a generation module, being configured to select at least one second pilot structure of a second super frame according to the pilot structure information and the at least one first pilot structure of the first super frame to generate the second super frame with the at least one second pilot structure; wherein the at least one second pilot structure is orthogonal to the at least one first pilot structure, the transceiver of the BS may communicates with the SS by the second super frame with the at least one second pilot structure to avoid a transmission interference between the BS and the another BS.
