摘要： A method and system for generating forward link channels in a synchronous CDMA base station having a pilot pseudonoise (PN) sequence with a pilot PN sequence offset. In one embodiment the method includes the steps of generating a sync channel including a sync channel message; generating an identification channel including at least the pilot PN sequence offset; and orthogonalizing the sync channel and the identification channel. The identification channel and the sync channel are both transmitted. However, the mobile station may get the pilot PN offset from the identification channel quickly, rather than having to demodulate the entire sync channel message. The identification channel may further include an indication of the phase of the pilot PN sequence, and the epoch of the pilot PN sequence. In one embodiment, the method includes encoding the identification channel using a Golay code.

摘要： A method and system that enables faster acquisition of the forward link signal of a target base station in a mixed network of synchronous and asynchronous base stations is disclosed. The serving base station transmits in a neighbor list an estimated timing error 417 between the serving base station and a target base station. By utilizing the timing information, a mobile station estimates the relative time offset 408 between forward link signals received from the serving base station and signals received from the target base station. Timing information acquired during handoff enables accurate updating of the estimated timing error 417 subsequently transmitted in the neighbor lists by the base stations.

摘要： An improved method for facilitating handoff between an asynchronous and a synchronous base station. A method for determining a pilot channel PN offset of a pilot channel transmitted by a wireless base station. In a first embodiment, the method includes correlating a PN sequence with a received pilot signal to acquire a PN frame timing, receiving at least one search code burst aligned with the PN frame timing, the at least one search code burst signifying the pilot channel PN offset, and comparing the at least one search code burst to a set of codewords, each codeword representing a predetermined PN offset. From the search code bursts, the mobile station is able to quickly determine the PN offset of the transmitting base station, and thereby identify it. Methods for transmitting a complementary set of forward link channels are also disclosed.

摘要： The invention is a method for limiting the peak transmit power in a CDMA communication system including the steps transmitting a first communication signal having a first high transmit power region and transmitting a second communication signal having a second high transmit power region. One of the first and second communication signals is time offset to prevent the first and second high transmit power regions from occurring simultaneously. Time shifting only a portion of one of the first and second communications signals is also taught. The first and second communication signals can also include respective first and second low transmit power regions. The time offset can be selected to align one of the first and second high transmit power regions with one of the first and second low transmit power regions.
