2 5 in another timeslot likewise ue b is assigned codes 0 13 in timeslots 8 and 9 and ue c is assigned code 11 in timeslots 11 and 12 to signal this assignment scheme to a ue an indication of the first and last codes of the consecutive codes is required as well as an indicator of the used timeslots step 86 for the system of fig6 eight 8 bits are required for the consecutive codes four 4 bits for the first code and four 4 bits for the last code or number of codes and twelve 12 bits to identify the used timeslot s each bit corresponds to a timeslot in one 1 implementation a one 1 bit value indicates that the timeslot is used and a zero 0 bit value indicates that it is not used thus a total of twenty 20 bits are required the use of prior signaled information and post signaled information with this method 80 reduces the number of prior signaled bits the prior signaled information must indicate the first used timeslot and the following timeslot and the first and last codes of the common sequence for the system of fig6 eight 8 bits indicating the first two 2 timeslots of the twelve 12 timeslots four 4 bits to indicate each timeslot and eight 8 bits for the start and end codes or number of codes thus a total of sixteen 16 bits of prior signaled information is required to further reduce the bits of the prior signaled information five 5 bits.
