Patent ID: 8233428

Claim:
A method of quick paging in a communication system that uses a plurality of subcarriers for orthogonal frequency division multiple access (OFDMA) and radio resources that include a first set of contiguous subcarriers corresponding to an available frequency bandwidth during a transmission symbol time period, comprising: transmitting a synchronization signal on every Nth subcarrier in the first set of contiguous subcarriers during the transmission symbol time period, N being a positive integer, such that periodicity of transmission of the synchronization signal is maintained over at least part of the available frequency bandwidth; and transmitting quick paging signals using orthogonal quick paging code words on subcarriers in the first set of contiguous subcarriers other than the Nth subcarriers during the transmission symbol time period, wherein the orthogonal quick paging code words include Walsh-Hadamard code words; simultaneously transmitting the synchronization signal and the quick paging signal using shared available radio resources during the same transmission symbol time period, and wherein transmitting a first quick paging code word indicates that a paging signal will be subsequently transmitted and transmitting a second quick paging code word indicates that the paging signal will not be subsequently transmitted.
