Title:
METHOD AND APPARATUS FOR SENDING SYSTEM INFORMATION IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/062773
Kind Code:
A3
Abstract:
Techniques for transmitting system information (SI) in SI messages to enable efficient reception by user equipments (UEs) are described. In an aspect, SI messages may be scheduled using both a forward space after a reference time and a backward space prior to the reference time to allow more SI messages to be scheduled. In one design, a base station may assign at least one SI message with at least one SI window in the forward space and may assign at least one additional SI message with at least one additional SI window in the backward space. The base station may determine the position of each SI window based on an index of the SI message, a periodicity of the SI message, and an SI window length common for all SI messages. The base station may send each SI message within the periodically occurring SI window for that SI message.
