Step 606, according to tone hopping information, relative position of the terminal in the first frequency hop sequences is determined.
Directly carry out frequency hopping according to total frequency hop sequences.
Step 608, whether terminal obtains available frequency point list by read system message, and judge initial frequency available
In frequency list, when judged result is to be, into step 610, when judged result is no, into step 612.
I.e. terminal is obtained by read system message can use frequency point sets, judge whether initial frequency is in available frequency point set
In conjunction, if it is, directly can be communicated using the initial frequency, if it is not, then can be by pre-defined rule, will be just
Beginning frequency is mapped to the frequency in available frequency point sets.
Step 610, communicated using the initial frequency.
Step 612, by pre-defined rule, the transmission frequency initial frequency being mapped in available frequency point list.Specifically,
The initial frequency can be mapped directly in available frequency point list, can also be by the initial frequency and frame number, subframe numbers, time slot
Number first doing predetermined operation re-maps in available frequency point list.
The pre-defined rule can be the corresponding relation for directly giving initial frequency and frequency in available frequency point sets, can incite somebody to action
The initial frequency is mapped directly in available frequency point sets.For example directly the complementation of counting out of initial frequency and available frequency is obtained
Remainder Y1, the initial frequency is mapped to Y1 available frequencies.
The pre-defined rule can also be that the initial frequency is first done into predetermined operation with frame number, subframe numbers, timeslot number to re-map
Into available frequency point sets., will for example complementation of being counted out again with available frequency after initial frequency is added with frame number obtains remainder Y2
The initial frequency is mapped to Y2 available frequencies.
Step 614, communicated using the transmission frequency in the available frequency point list.
The technical scheme, it is first to generate frequency hop sequences according to total frequency number, and frequency hopping is carried out in total frequency number, according still further to
Available frequency point list changes frequency hopping frequency.
