applications TDMA based MAC scheduling is considered an attractive option. ..... (8) where xt|t is estimate of xt given observation and predicted value at time t, γ2 t| t is the mean ... protocol, each node allocates a time slot and selects its frame. OpenBTSTime_Division_Multiple_Access_(TDMA) Each time slot lasts 576.9 µs. A time slot is the basic radio resource used to facilitate communication between the MS and the BTS.This burst is used for time synchronization of the mobile. The data payload carries the TDMA Frame Number (FN) and the Base Station Identity Code (BSIC). TDMA Time Slots / Multiplexing Time Division A TDMA frame contains small time slots where each radio is allowed to transmit in. The slots are sequentially numbered.TDMA Frames have a pre-set number of slots, and once the TDMA Frame Time has passed, the frame restarts at slot 0 again.

The FCMS only contains a frame control frame which is a broadcast message from the RSE indicating the number of slots, the type of each slot and the size of the slots that compose the rest of the TDMA frame.

NTC CTXX 2415 Issue 2. The TDMA frame consists of 8 time slots.
• If GSM uses a frame structure where each frame consists of 8 time slots, with each time slot of 156.25 bits, and data is transmitted at 270.833 kbps. • The time duration of a bit is 𝑏= 1 270.833 𝑏 =3.692 • The time duration of a slot is =156.25× 𝑏=0.577 𝑚
A GSM Multiframe is the basic unit, and is 120 ms long. There are 26 Frames in each Multiframe, with each Frame being 4.61538 ms long (120 ms/26). Within each Frame are 8 Timeslots at 576.92 μs per Timeslot (577 μs in round numbers). Finally, there are 156.25 Bits per Timeslot, each Bit being 3.69231 μs long. Time Division Multiple Access TDMA - Voice Channels Figure 18.8 A typical TDMA frame. Figure 18.8 A typical TDMA frame. case, only one carrier is required. Each user gains access to the carrier for 1/n of the time and there is generally an ordered sequence of time slot turns. TDMA, FDMA, and CDMA - uniroma1.it TDMA : Frame Structure TDMA requires a centralized control node, whose primary function is to transmit a periodic reference burst that defines a frame and forces a measure of synchronization of all the users. The frame so-defined is divided into time slots, and each user is assigned a Time Slot in which to transmit its information. T F T S ...

TDMA • Data bursts transmit in time-slots of 417 µ s • Total 12 uplink and 12 downlink channels in 24 slots in a total duration of 10 ms • After each successive 10 ms interval, the slots in a frame are repeated • Uplink and downlink frequencies can now be kept identical, as the time-slots used for them are distinct ©
