`
`The Air Interface in GPRS
`
`3.1 The 52 Multiframe
`
`In the first chapter, we paid special attention to describing the frame hierarchy
`with 26 multiframe and 51 multiframe. One of the reasons for this is the
`definition of an additional multiframe type especially for GPRS. This new
`52 multiframe with a period of exactly 240 ms is essential for understanding
`the resource administration and operation of GPRS.
`Note that the 52 multiframe corresponds in terms of period to exactly
`two consecutive 26 multiframes as illustrated in Figure 3.1. F~r this reason,
`the function of synchronizing the mobile station to the BTS does not have
`to be altered (see also 1.6.6.1). In short, the 52 multiframe number is
`obtained by halving the 26 multiframe number. The current GPRS burden
`determines how many time slots on which ARFCNs traverse the 52
`multiframe instead of the 26 multiframe and 51 multiframe. At a given
`point, there may only be one time slot configured for GPRS, which means
`using the 52 multiframe, whereas later, all eight time slots may be reserved
`on this frequency for GPRS and therefore configured with the 52 multiframe.
`Whatever the case may be, GPRS and GSM cannot coexist on one time
`slot. Depending on the burden, the services are switched from one to the
`other. We are pointing this out so clearly here because this is one of the
`most frequently asked questions in our GPRS courses.
`
`3.1.1 Structure and Multiplexing on the 52 Multiframe
`The decisive factor for GPRS is the division of a 52 multiframe into 12
`radio blocks, where each radio block is four repetitions of the same time

`
`slot. Figure 3.2 shows the fine structure of the 52 multiframe with the 12 radio
`blocks and the TDMA frames for timing advance control and interference
`measurements.
`It is the radio blocks that constitute the atomic resource unit of GPRS.
`While a user in GSM always receives a complete time slot as a resource for
`data transmission, only radio blocks, as parts of time slots, are allocated in
`GPRS. In this way, several subscribers can share a single time slot. A further
`peculiarity of GPRS is that the resources in the uplink and downlink direc(cid:173)
`tions are almost completely independent from one another. In particular,
`the allocation of radio blocks for data transmission in GPRS is either uplink
`or downlink. Of course, bidirectional data transmission is also possible and
`is used. These, however, require two resource allocations, one per direction.
`There is no certainty that a subscriber will be allocated the same time
`slot(s) for transmission in both directions. This depends in particular on the
`multislot class of his device.
`In other words, a subscriber only receives the resources that are actually
`needed at any given time in accordance with the resource on demand concept

`
`of packet switched data transmission. Here, a single time slot in each direction
`can be used almost simultaneously by several subscribers.
`At this point, it is often asked how many subscribers can be allocated
`resources simultaneously on one time slot and per direction. It is still too
`early to answer this question. However, we would like to point out that in
`accordance with the 52 multiframe period, not more than 12 subscribers
`can use the same time slot within 240 ms and per direction. The transmission
`rate is also accordingly low in such a case.
`Mixed configurations on an ARFCN are of course also possible-in -
`fact, they are predominant. As Figure 3.3 illustrates, several time slots for
`circuit switched GSM can be configured on one frequency, while GPRS
`subscribers share the other time slots.

`Resource allocation in GPRS will be discussed in a later section.
