PREAMBLE STRUCTURE AND ACQUISITION FOR A WIRELESS COMMUNICATION SYSTEM
First Claim
1. An apparatus comprising:
- at least one processor configured to receive a plurality of pilots in a plurality of time intervals, the plurality of pilots carrying different sets of bits for information sent in the pilots, each set including some or all bits of the information, and to perform detection to recover a set of bits sent in each of the plurality of pilots; and
a memory coupled to the at least one processor.

Abstract
Techniques for sending sector/system information in TDM pilots using a hierarchical pilot structure are described. A base station sends multiple sets of bits for the sector/system information in multiple TDM pilots. The set of bits sent in a given TDM pilot may include bits sent in earlier TDM pilots. In one design, the base station generates a first TDM pilot based on a first set of bits, generates a second TDM pilot based on a second set of bits that includes the first set, generates a third TDM pilot based on all bits for the information, and sends the TDM pilots. A terminal performs detection to obtain a first detected value for the first TDM pilot, performs detection based on the first detected value to obtain a second detected value for the second TDM pilot, and performs detection based on the first and second detected values to obtain a third detected value for the third TDM pilot.
