 mode transmit diversity requires that the S field consists of 1 bit. The use of the FBI fields is described in detail in [5]. Table 4.4 DPDCH Fields Channel bit Channel symbol Bits/frame Bits/slot Ndata format #i rate (kbps) rate (ksps) There are two types of uplink dedicated physical channels; those that include TFCI (e.g. for several simultaneous services) and those that do not include TFCI (e.g. for fixed-rate services). These types are reflected by the duplicated rows of Table 4.5. It is the UT- RAN that determines if a TFCI should be transmitted and it is mandatory for all UEs to support the use of TFCI in the uplink. The mapping of TFCI bits onto slots is described in [3]. In compressed mode, DPCCH slot formats with TFCI fields are changed. There are two possible compressed slot formats for each normal slot format. They are labelled A and B and the selection between them is dependent on the number of slots that are transmitted in each frame in compressed mode.

The shadowed column part of pilot bit pattern is defined as FSW, which can be used to confirm frame synchroniza- tion. (The value of the pilot bit pattern other than FSWs shall be '1'.)
