multi-slot class 10 ¶įor example, a phone with EDGE multislot class 10 permits for a total of 5 active time-slots, which can be either 4+1 (4 downlink, 1 uplink) or (3+2) (3 uplink, 2 downlink). The capabilities of each phone are specified as so-called multislot classįor a table of multislot classes, please see 3GPP TS 45.002, or a summarized version at wikipedia. Normally, phones can not decode all 7/8 time-slots, as they operate in half-duplex mode and need some time for transmit, too. On the MS (phone) side, things are not that simple. If you're running a single-TRX small BTS, the first timeslot is always allocated for the BCCH/CCCH, leaving 7 time-slots available for voice (TCH) and data (PDTCH).įor example, a total of 7 time-slots in MCS-9 coding scheme would render MCS-9 has no error correction coding at all, but t GPRS channel coding ¶Įach of the 8 GSM time-slots can operate i a number of different coding schemes:īTS equipment is normally capable to run all timeslots in GPRS mode. The lower numbers (CS-1/MCS-1) have the most error coding and are very contention on the radio channel / resource sharing by multiple phonesĭepending on the characteristics of the radio channel (interference, bit errors, link quality, C/I), the network willĭynamically select the best coding scheme.

channel coding, which in turn depends on.There are multiple aspects that relate to the problem Features: EDGE (E-GPRS) Multislot class 10 GPRS Multislot class 12 GSM release 99 Output power: class 4 (2 W) for EGSM850 class 4 (2 W) for EGSM900 class. This page tries to outline the possible achievable GPRS bit-rates.
