  • Patent number: 9642152
    Abstract: A resource allocation method and base station. The resource allocation method comprises: within a current scheduling period, determining priorities of users in a cell for sub-carriers in available frequency resources, and among the available frequency resources of the cell, allocating a corresponding available frequency resource for each user in the cell according to the priorities of all users for the sub-carriers, so that the frequency resources that can be used by the edge users cover all available frequency ranges of the cell. Therefore, when frequency selectivity fading occurs in the channel, a decline in communication quality caused by allocating carrier resources for the edge users in the limited frequency resources is avoided, the probability that the edge users use deeply fading frequency resources is reduced, and interruption in the communication process is decreased, thereby improving system throughput.

  • Patent number: 9565700
    Abstract: A method at a base station of determining a time delay associated with a mobile station in a multiple access wireless communication system. A signal is received from a mobile station over a selected random access subchannel in a selected random access time slot. A Fast Fourier Transform is applied to the received signal to generate a transformed signal in the frequency domain. The transformed signal is then processed in the frequency domain by computing a dot-product to identify a random access sequence carried in the received signal. The received signal is then processed in the time domain by computing a correlation between a time-shifted version of the received signal and the identified random access sequence to determine a time delay associated with the mobile station.
