Abstract  Abstract

In a first mode of dedicated control channel (DCCH) operation a wireless terminal is allocated more segments than in a second mode. The wireless terminal uses different information bit to modulation symbol mapping in the different modes. On a per DCCH segment basis the same number of modulation symbols are communicatd in either mode but more information bits are conveyed in the second mode. Information bits for a DCCH segment are partitioned into two subsets. The two subsets are used to generate another set each of the two subsets and the another set are input to the same mapping function to generate three equal size sets of modulation symbols which are transmitted via the DCCH segment. Uplink tone hopping is used such that one of the equal size sets of modulation symbols for the DCCH segment uses the same tone but a different set uses a different tone.
