Title:
METHOD AND APPARATUS FOR DETERMINING TRANSMISSION TIME-FREQUENCY RESOURCES OF TRAFFIC DATA
Document Type and Number:
WIPO Patent Application WO/2016/020751
Kind Code:
A3
Abstract:
The invention provides a method of determining transmission time-frequency resources of traffic data in a wireless communication network. The network device determines a time-domain transmission pattern Pi, j of the traffic data from a time-domain transmission pattern set PI, J; determines a frequency hopping pattern of the traffic data based on a frequency hopping matrix and a first rule, wherein the frequency hopping matrix is constructed by one or more Latin squares, a number of rows of the frequency hopping matrix is equal to a number of sub-bands in a frequency hopping bandwidth, each element in a row of the frequency hopping matrix successively represents a frequency hopping order of the complement transmission patterns Pi, j and Pi, j', a number of columns of the frequency hopping matrix is equal to a number of transmissions of the traffic data, and the first rule is Pi, j and Pi, j' are assigned with a same channel within a sub-band and a value of j is a part of J or all of J, the complement transmission patterns Pi, j and Pi, j' in the transmission pattern subset Pi, J are assigned with a same channel within a sub-band and use a same sub-band for their first transmission, the non-complement transmission patterns Pi, j and Pi, k in the transmission pattern subset Pi, J have a same relative location in each sub-band and the non-complement transmission pattern subsets Pi, J and Ps, J are assigned with the different channels within a sub-band; and sends the traffic data according to the time-domain transmission pattern Pi, j and the frequency hopping pattern.
