45、els that can be separated into two categories as defined in GSM 04.03: i) the traffic channels (TCHs); ii) 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 the present do
46、cument 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. 3 3.1 Logical channels General This clause descri
47、bes the logical channels that are supported by the radio subsystem. 3.2 Traffic channels 3.2.1 General Traffic channels (TCHs) are intended to carry either encoded speech or user data in circuit switched mode. Two general forms of traffic channel are defined: i) Full rate traffic channel (TCWF). Thi
48、s channel carries information at a gross rate of 22,s kbids. ii) Half rate traffic channel (TCWH). This channel carries information at a gross rate of 11,4 kbids. iii) Enhanced circuit switched full rate traffic channel (E-TCWF). This channel carries information at a gross rate of 69,6 kbids includi
49、ng the stealing symbols. Packet data traffic channels (PDTCHs) are intended to carry user data in packet switched mode. For the purpose of the present document, any reference to traffic channel does not apply to PDTCH unless explicitly stated. All traffic channels are bi-directional unless otherwise stated. Unidirectional downlink full rate channels, TCWFD, are defined as the downlink part of the corresponding TCWF. Multiple full rate channels can be allocated to the same MS. This is referred to as multislot configurations, which is defined in clause 6.4.2.1. Multiple packet data
