A method is described of controlling a communication system using a continuous FDD channel. Each time segment of the channel is divided into a predetermined number of sub-segments. For a first set of time segments, the communication signal data for the respective time segment is repeated in all sub-segments, and for a second set of time segments, null periods are provided in one or more of the sub-segments during which the communication signal from the first station to the second station is interrupted. The communication signal data is transmitted during the remaining sub-segments of the second set. This approach enables a slotted transmission mode to be established in a CDMA FDD system, without the need to adapt the spreading ratio of the CDMA system.
A method of controlling a communication system in which a communication signal is established between first and second stations and using a channel configuration comprising sequential time segments with the channel defining a substantially continuous transmission, comprising:
A telecommunication station for transmitting a signal over an allocated channel which is divided into time segments, comprising transmitting means, timing means for dividing the time segments into sub-segments, repeating means for allocating communication signal data to a plurality of sub-segments, and interrupting means for arranging one or more sub-segments as null periods during which transmission is interrupted, wherein for a first set of time segments the repeating means allocates the communication signal data to all sub-segments for transmission at a first power, and wherein for a second set of time segments the interrupting means arranges one or more sub segments of each time segment as a null period and the repeating means allocates the communication signal data to the remaining sub-segments of the second set for transmission at a second power which is greater than the first power.
A telecommunication station for receiving a signal from a transmitting station over an allocated channel which is divided into time segments with the time segments divided into a predetermined number of sub-segments, comprising receiving means, means for interrupting operation of the receiving means during sub-segments arranged as null periods, means for combining data in sub-segments arranged as repeated data of individual time segments, and means for operating the receiving means to survey other communication channels during the null periods.
