Abstract
An example technique may include receiving, by a mobile station from a cell, a first block of symbols and a second block of symbols, each of the first and second blocks of symbols including a plurality of contiguous segments that include a plurality of symbols, performing, by the mobile station, a short correlation of each segment of the first block of symbols with a corresponding segment of the second block of symbols to obtain a plurality of segment correlation results, determining a block correlation result for the first block of symbols and the second block of symbols based on summing at least a first subset of the segment correlation results and subtracting a second subset of the segment correlation results.

A method of acquiring timing information in a wireless network, the method comprising:
- receiving, by a mobile station from a cell, a first block of symbols and a second block of symbols, each of the first and second blocks of symbols including a plurality of contiguous segments that include a plurality of symbols;
- performing, by the mobile station, a short correlation of each segment of the first block of symbols with a corresponding segment of the second block of symbols to obtain a plurality of segment correlation results;
- determining a block correlation result for the first block of symbols and the second block of symbols based on summing at least a first subset of the segment correlation results and subtracting a second subset of the segment correlation results.
An apparatus comprising at least one processor and at least one memory including computer instructions, when executed by the at least one processor, cause the apparatus to:
- receive, by a mobile station from a cell, a first block of symbols and a second block of symbols, each of the first and second blocks of symbols including a plurality of contiguous segments that include a plurality of symbols;
- perform, by the mobile station, a short correlation of each segment of the first block of symbols with a corresponding segment of the second block of symbols to obtain a plurality of segment correlation results;
- and
- determine a block correlation result for the first block of symbols and the second block of symbols based on summing at least a first subset of the segment correlation results and subtracting a second subset of the segment correlation results.

- multiplying each of the segment weights by an associated segment of the second block to obtain weighted segments of the second block;
- performing, by the mobile station, a short correlation of each segment of the first block of symbols with a corresponding weighted segment of the second block of symbols to obtain a plurality of segment correlation results;
- and
- determining a block correlation result for the first block of symbols and the second block of symbols based on summing the segment correlation results.
