Uplink Control Channels Physical Resource Mapping
Fast Feedback Control Channel
There are two types of UL fast feedback control channels: primary fast feedback channel (PFBCH)
and secondary fast feedback channels (SFBCH).
15.3.9.2.1.1.
Primary Fast Feedback Control Channel
The primary fast feedback channels are comprised of 3 distributed FMTs. Figure UL-3 illustrates the
mapping of the PFBCH.

Figure UL- 2, Mapping of information in the PFBCH.
The process of composing the PFBCH is illustrated in Figure UL- 2. The l PFBCH payload bits are used to
generate PFBCH sequence according to Table UL- 1. The resulting bit sequence is modulated [, repeated] and
mapped to uplink PFBCH symbol s[k]. The mapping of primary fast feedback channel symbol s[k] to the UL
FMTs is given by Eqn. UL- 1. This set of sequence can carrier up to 6 information bits.
