    • Portable stations with a single receiver can perform communication using a plurality of slots in one frame in time division multiple access (TDMA) transmission. When communication is performed between one of the portable stations and a cell station with data of two 32 kbps data into which an exchange converts one 64 kbps data, the portable station occupies two slots in one TDMA frame. A controller of the cell station assigns these two slots as being separated from each other by at least one slot. Alternatively, the controller assigns these two slots as being adjacent to each other and assigns same carrier frequency to these slots. Thus, communication with a transmission rate of 63 kbps can be performed by using two slots or two channels of 32 kbps.
    • 具有单个接收机的便携式站可以在时分多址(TDMA)传输中使用一帧中的多个时隙进行通信。 当在一个便携式站和具有两个32kbps数据的数据的小区之间进行通信时,交换机转换一个64kbps数据,便携式站占用一个TDMA帧中的两个时隙。 小区的控制器将这两个时隙分配成彼此分开至少一个时隙。 或者,控制器将这两个时隙分配为彼此相邻并且向这些时隙分配相同的载波频率。 因此,可以通过使用32kbps的两个时隙或两个信道来执行具有63kbps的传输速率的通信。
