METHODS AND APPARATUS TO ALLOCATE REFERENCE SIGNALS IN WIRELESS COMMUNICATION SYSTEMS |
摘要 |
Methods and apparatus to allocate reference signals in wireless communication systems are disclosed. A disclosed example apparatus comprises a reference signal generator (501) to generate a reference sequence (505) based on a parameter assigned to a wireless region, wherein the parameter specifies a first reference sequence to be transmitted by a first device of the wireless region during a first time interval, the first reference sequence being different from a second reference sequence assigned to a second device of a second wireless region adjacent to the first wireless region. The reference sequence generator comprises a cyclic shift selector (503) to select a cyclic shift for the first time interval based on the parameter and a cyclic shifter (506) to cyclically shift the first reference signal based on the selected cyclic shift. The example apparatus further comprises a transmit adapter (510) to transmit the cyclically shifted first reference sequence. |
