Frame Structure - Time Domin
Following is the overall frame structure for 1.28Mcps options.
1. one radio frame is 10ms length.
2.one radio frame is made up of 2 subframes and each of these subframes has 5ms length.
3.the two subframe structure within a radio frame has same structure
4.each subframe has 7 timeslots in it
5.length of each time slot is 864 chips
6.among the 7 traffic time slots, time slot 0 is always allocated as downlink and time slot 1 is always allocated as uplink.
7.there must be at least one downlink slot and at least one uplink slot within a subframe.
As long as this requirements is met, you can create any combination of uplink and downlink slots.
8.In a multi-frequency cell, it is suggested the switching point
conifguration on secondary frequency to be the same as that on the primary
frequency.
