Two types of MSs are defined: type 1 mobiles are not able to transmit and to receive at the same time, while type 2 mobiles are. If there are m time slots allocated to an MS for reception and n time slots allocated for transmission, the system requires that min ( m,n) reception and transmission time slots have the same time slot number (TN see Section 1.5.1 for the definition) within the TDMA frame. Several bursts can be transmitted within a TDMA frame, but should all be on the same ARFC number (ARFCN i.e., the same carrier frequency).ĭepending on the mobile capability, delay constraints are needed between the transmission and reception of bursts, and between reception and transmission, to allow the mobile to perform the adjacent cell measurements, or monitoring, as discussed in Chapter 1. ![]() In order to do so with a reasonable impact on the MS in terms of implementation complexity, it has been decided to allow the RF transmission on several slots of a TDMA frame, with a number of restrictions, as listed below. One of the most important GPRS characteristics on the air interface is the possibility of increasing the achievable bit rate by grouping together several channels. ![]()
