First Claim
Patent Images
1. A method of broadcasting system information in a Long Term Evolution (LTE) mobile communication system, the method comprising:
- classifying the system information into a first portion and a second portion based on characteristics of the system information, the first portion comprising scheduling information;
broadcasting the first portion of the system information via a first type of common transport channel; and
transmitting the second portion of the system information via a second type of common transport channel based on the scheduling information,wherein the first type of common transport channel is a Broadcast Channel (BCH) which is a statically scheduled common transport channel,wherein the second type of common transport channel is a Downlink Shared Channel (DL-SCH) which is a flexibly scheduled common transport channel, andwherein broadcasting the first portion of the system information comprises broadcasting the first portion using not more than half of a cell bandwidth of the LTE mobile communication system.
