1 Scope p. 8

The present document defines the physical channels of the radio sub system required to support the logical channels. For the Flexible Layer One, it defines the physical channels of the radio sub system required to support the transport channels. It includes a description of the logical channels, transport channels and the definition of frequency hopping, TDMA frames, timeslots and bursts.

1.3 Restrictions |R9| p. 9

Independently of what is stated elsewhere in this and other 3GPP specifications, mobile station support for PBCCH and PCCCH is optional for A/Gb-mode of operation. The network shall never enable PBCCH and PCCCH.

2 General p. 9

The radio subsystem is required to support a certain number of logical channels that can be separated into two categories as defined in TS 44.003:

the traffic channels (TCH's);
the control channels.

More information is given about these logical channels in clause 3 which also defines a number of special channels used by the radio sub system.

Clause 4 of this document describes the physical resource available to the radio sub system, clause 5 defines physical channels based on that resource and clause 6 specifies how the logical channels shall be mapped onto physical channels. Figure 1 depicts this process.

With the Flexible Layer One (FLO), the radio subsystem is required to support transport channels (see TR 45.902). Clause 8 of this document describes the mapping and multiplexing principles that are specific to FLO. Because FLO offers transport channels instead of logical channels, any reference to logical channels, with the exception of SACCH, does not apply to FLO. Otherwise, and unless otherwise stated, the multiplexing principles described in this document are equally applicable to FLO (e.g. physical resource and physical channels).
