摘要： In TDMA systems it is possible to transmit data on more than one consecutive slot per frame. This introduces increased workloads on the power amplifier of the transmitter of the mobile station. To prevent the power amplifier from overheating, temperature sensing means are incorporated into the mobile station which output to a control system comprising a comparator and feedback means which together regulate the operation of the transmitter if the power amplifier approaches or exceeds its upper rated operating value, thereby preventing the power amplifier from damage.

摘要： According to the present invention there is provided a method of transmitting user data in a TDMA system in which the number of channels is increased by partitioning at least one time-slot in a TDMA frame into at least two sub-time-slots. Each sub time-slot may be allocated to a different user. User data may be transmitted in each time slot in a burst structure, user data being transmitted in each sub time-slot in a corresponding burst structure. User data may be transmitted in each time slot in a burst structure having n bits and wherein each time slot is partitioned into m sub time slots, user data being transmitted in each sub time-slot in a corresponding burst structure having n/m bits.

摘要： This invention relates to radio communications and in particular relates to a method for allocating channels in a radio communications system having a plurality of bearers in a system which is subject to slow temporal fading. In radio communications, signals are transmitted at a particular frequency, in a frequency band or in a number of frequency bands. Obstacles in a signal path, such as buildings in built-up areas and hills in rural areas, act as signal scatterers and these, together with fading, amongst other factors can cause signalling problems whereby signals may not be communicated on certain channel The present invention provides a system and method for channel allocation method for a multi-bearer communications network, with each bearer supporting a number of channels, wherein after allocation of a channel responsive to an access request from the available bearers which can provide access, the maximum number of available slots are left on each bearer, for a particular level of subscription.

摘要： A burst detector (140) detects the occurrence of a burst in a signal receiver. A filter (220) having an impulse response characteristic of an expected burst filters a received signal. A subtractor (230) subtracts a filtered version of the received signal from a delayed and filtered version of the received signal to provide a detection signal. A burst edge detector (250) detects a leading edge of the burst based on the detection signal.

摘要： A master station and at least one slave stations are connected by radio channels, and each slave station transmits data to the master station by time division multiple access. First means equally divides a prescribed area, which is defined in a burst signal for use in transmission from each slave station to the master station and intended for arrangement of message signals sent from at least one terminal connected to the slave station, into at least two sub-areas, and arranges a message signal in each sub-area. Second means generates a burst signal, in which at least a control signal and a channel quality monitoring signal are arranged, in the area peripheral to each sub-area in which a message signal is arranged. Here the prescribed area in the burst signal is an area corresponding to a data quantity of 64 kbps in transmission speed. The data quantity of the message signal arranged in that area corresponds to data of 32 kbps, 16 kbps or 8 kbps in transmission speed.

摘要： An object of the invention is a method of measuring neighbouring cells in a TDMA cellular radio network using time hopping. A base station sends common control channels (CCCH) in at least one time slot of a TDMA frame down-link to a subscriber terminal. The subscriber terminal measures a neighbouring cell from the at least one time slot of the TDMA frame, the slot containing a common control channel (CCCH). The invention is characterized in that the at least one time slot to be measured of the TDMA frame, the slot containing a common control channel (CCCH), is transmitted without time hopping at a constant transmission power. A further object of the invention is a TDMA cellular radio network using time hopping.

摘要： A time division multiplex communication control system for controlling assignment of communication channels (C) from a switching office (10) to mobile stations (20) in which control on the switching office side is automatically effected so that communication channels having a high likelihood of communication disturbances are lastly assigned. In one embodiment, the communication channels (C0, C1) located immediately before and behind the control channel (C1) and having a high likelihood of communication disturbances from control channel signals are lastly assigned. In another embodiment in which two carriers (1, 2) are available and the control channel (C1) is located in the first carrier (1), communication channels (5) in the second carrier are first automatically assigned and, when a communication channel (5) is not available in the second carrier (2), a communication channel (C) is the first carrier (1) which is not adjacent the control channel (C1) is assigned.
