Device and method for discovery channel hopping scheme

摘要

A device and method generates a hopping scheme for mobile stations of a wireless network. The method includes receiving a number of channels N of the wireless network. The method includes generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of the mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme. The method includes generating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix. The hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.

1. A method, comprising:
at a mobile station:
receiving a number of channels N of a wireless network;generating a shuffling matrix as a function of the number of channels N, each row of the shuffling matrix being indicative of a respective one of a plurality of mobile stations, each column of the shuffling matrix being indicative of a respective broadcast time of a discovery signal in a hopping scheme; andgenerating the hopping scheme for the mobile stations in the channels as a function of the shuffling matrix,wherein the hopping scheme dynamically maps a physical resource of the mobile station to one of the channels,wherein the hopping scheme is generated such that each channel hops across all of the physical resources with substantially equal frequency, andwherein the hopping scheme maximizes an interval between two consecutive broadcast times that any two of the mobile stations are assigned to transmit discovery signals on adjacent channels.
