LOW REUSE PREAMBLE FOR A WIRELESS COMMUNICATION NETWORK

摘要

Techniques for sending low reuse preambles in a wireless network are described. In an aspect, a base station sends a low reuse preamble on reserved frequency resources to allow terminals to detect the base station even in the presence of strong interfering base stations. The base station generates the low reuse preamble to include a pilot portion and a data portion. The base station determines frequency resources reserved for sending low reuse preambles by base stations. The base station then sends the low reuse preamble on the reserved frequency resources, e.g., at a pseudo-randomly selected time. A terminal detects for low reuse preambles sent by the base stations on the reserved frequency resources. The terminal recovers information for a base station from a detected low reuse preamble.
