Abstract
A method of wireless communication including a base station transmitting a preamble including information indicating a sector identifier and an antenna port value. The base station further transmits a pilot sequence, wherein the pilot sequence and the location of the pilot sequence are based on the sector identifier and on the antenna port value. A base station configured to perform the method is also disclosed. A corresponding subscriber station configured to receive the preamble and pilot sequence is also disclosed, as well as a subscriber station method.
Claims22
A method comprising:
- receiving, by a client station, an orthogonal frequency division multiple access (OFDM) signal, from a base station for use in cell search, the OFDM signal including a primary signal, a secondary signal and a pilot signal, the primary signal having a first pseudo random sequence, the secondary signal having a second pseudo random sequence and the pilot signal having a third pseudo random sequence;
- determining an identity of a cell, by the client station, based on at least the second pseudo random sequence of the secondary signal;
- and
- determining an antenna configuration identification based on the third pseudo random sequence of the pilot signal.
A client station comprising:
- a receiver configured to receive an orthogonal frequency division multiple access (OFDM) signal, from a base station for use in cell search, the OFDM signal including a primary signal, a secondary signal and a pilot signal, the primary signal having a first pseudo random sequence, the secondary signal having a second pseudo random sequence and the pilot signal having a third pseudo random sequence;
- and
- a processor configured to determine an identity of a cell based on at least the second pseudo random sequence of the secondary signal;
- and
- determining an antenna configuration identification based on the third pseudo random sequence of the pilot signal.
