37、tween User Equipment (UE) and network. The radio interface is composed of Layers 1, 2 and 3. Layer 1 is based on WCDMA/TD-SCDMA technology and the TS 25.200 series describes the Layer-1 specification. Layers 2 and 3 of the radio interface are described in the TS 25.300 series. Figure 1: Radio interf
38、ace protocol architecture around the physical layer Figure 1 shows the UTRA radio interface protocol architecture around the physical layer (Layer 1). The physical layer interfaces the Medium Access Control (MAC) sub-layer of Layer 2 and the Radio Resource Control (RRC) Layer of Layer 3. The circles
39、 between different layer/sub-layers indicate Service Access Points (SAPs). The physical layer offers different Transport channels to MAC. A transport channel is characterized by how the information is transferred over the radio interface. MAC offers different Logical channels to the Radio Link Contr
40、ol (RLC) sub-layer of Layer 2. A logical channel is characterized by the type of information transferred. Physical channels are defined in the physical layer. There are two duplex modes: Frequency Division Duplex (FDD) and Time Division Duplex (TDD). In the FDD mode a physical channel is characteriz
41、ed by the code, frequency and in the uplink the relative phase (I/Q); in addition E-HICH and E-RGCH are also defined by a specific orthogonal signature sequence. In the TDD mode the physical channels are also characterized by the timeslot and additionally, the E-HICH is further defined by a specific
42、 orthogonal signature sequence. For 1.28Mcps TDD, the E-HICH can be also further defined by a group of orthogonal signature sequences. The physical layer is controlled by RRC. 4.1.2 Service provided to higher layers The physical layer offers data transport services to higher layers. The access to th
43、ese services is through the use of transport channels via the MAC sub-layer. The physical layer is expected to perform the following functions in order to provide the data transport service.

UTRA has two modes, FDD (Frequency Division Duplex) for the 7.68Mcps TDD option, scrambling codes with length 32 are used. - For separating different UEs the following code families are defined. - FDD mode: Gold codes
