    Abstract: A time division multiple access communication system is disclosed, in which down link data are transmitted over a data channel in repeated time frames each containing a plurality of time slots. Down link set up information is transmitted over a control channel to indicate from which time slot a user terminal should extract data. Each frame on the data channel includes a user packet flag to indicate whether or not each time slot in the frame contains data. Each user terminal is responsive to the set up information and to the user packet flags to extract data from its assigned time slot in those frames which the slot is indicated to contain data.

    Abstract: A method of detecting the format of received information by detecting the format of a guiding channel of a communication system. With the use of a lookup table or other mapping technique, the detected guiding channel format is used to determine the format of the other channels of the communication system. Therefore, the format of received information can be determined without the use of TFCI information.

    Abstract: There is disclosed a method of transmitting data in a code division multiple access system, comprising the steps of: outputting data blocks associated with a plurality of respective users in a plurality of corresponding data streams, the data blocks of each data stream being arranged in successive time frames of a constant, predetermined length; and multiplexing the data blocks on all the data streams for each given time frame. A communications system including circuitry for utilising such a method is also disclosed.

    Abstract: In a CDMA network, each mobile is arranged to combined pilot symbols from its dedicated pilot channel with pilot symbols from at least one common channel as an input to its channel impulse response sensing means. The common channel may be a BCH, a FACH or a PCH, and the pilot symbols on all such channels may be combined. The pilot energy required on each dedicated pilot channel can thereby be reduced. By communicating the quality of the received pilot symbols to a base station, the base station can reduce the energy on the dedicated pilot channel, providing a yet further saving of energy.
