Abstract: PROBLEM TO BE SOLVED: To provide a TDMA communication system capable of carrying out downlink adaptive beam formation and downlink power control. SOLUTION: An allocation message includes an identification code for allocating users to the prescribed slots of the frames of an uplink and a downlink, and the allocation message is transmitted to users in all the sections of the slot of the first frame of the down link block of the frame. By using the corresponding slot of a following downlink frame after that, information is transmitted to the users and downlink adaptive beam formation and downlink power control are carried out at the same time. The users use the corresponding slots of an uplink frame to send the information to system equipment. Conventional users can use the system while other users can transmit and receive information by this system.

Abstract: PROBLEM TO BE SOLVED: To provide an information transmission device that reduces an IER (information error rate) of a communication network under an established standard, without the need for substantial correction of user and system devices. SOLUTION: The device 400 is provided with a selector device 416, connected to a framer 402 and with an interleaver 414. The interleaver 414 is connected to the framer 402 and to communication units 404-412 that are normally used for processing user information. The framer 402 groups the user information into information groups and generates copies of each information group, on the basis of system information received by the selector device 416. The interleaver 414 receives the generated information group. The interleaver 414 interleaves generated frames over time blocks, whose number is selected in a communication network, on the basis of the system information that the selector device 416 receives.

Abstract: PROBLEM TO BE SOLVED: To interleave information so that de-correlation existing in a communication channel for transmitting information can be used as much as possible without extending delay time so much when information is transmitted. SOLUTION: In this method for interleaving information transmitted through a wireless communication system, respective information blocks are separately divided before interleaving for uniformly dividing the information blocks and shortening delay time. The prescribed part of the information block transmitted by a user is transmitted between allocated time slots. The remaining part of the information block is transmitted to one another time slot with the part of the different information block of the user. The time slot is selected so that time required for transmitting the whole information blocks is prevented from remarkably increasing compared to a conventional interleaving method.

Abstract: PROBLEM TO BE SOLVED: To assign a network device of a cellular communication system to a different user assigned to a specific cell and to increase the capacity of the communication system without deteriorating the quality of communication served to users of the system thereby. SOLUTION: A signal of a user is received and the strength of the signal is determined. The user is assigned to a 1st type or a 2nd type of a network user based on an upper or lower threshold of the signal of the user. A network provider defines the threshold. When the signal strength is lower than a 2nd threshold, the user is handed off to other network device of an adjacent cell. Thus, the communication system can increase the capacity while maintaining the quality permissible of communication to the user.

Abstract: PROBLEM TO BE SOLVED: To provide operation information for a traffic radio which serves active channels by scanning the active channels of a base station. SOLUTION: Active channels of a base station are scanned by measuring radio 614 (614A, 614B) to measure operation information of radio 612A to N, i.e., the signal intensity, BER(bit error rate), FER(frame error rate), signal-to- interference radio (C/I), etc. According to the operation information, the traffic radio 612A to N determine whether or not the method for servicing the active channels is to be changed or not. For example, when difference antenna sets 620A to N can be switched, the measuring radio 614 scans active sound/data channels by using an antenna set different from the current antenna set to serve the active channels and determines the operation information regarding a received signal. The measuring radio 614 can determine operation information on an operation coefficients, parameters, settings, etc., and change the active channels that the traffic radio 612A to N are using.

Abstract: A method for interleaving information to be conveyed over a TDMA wireless communication system. A certain portion of information associated with a user is transmitted during one time slot and the remaining information for that user is intermingled with other information for that user and transmitted in a subsequent time slot.

Abstract: A wireless endpoint employs frequency hopping for communicating signals in a wireless communications system. Over a time period T, the wireless endpoint performs pseudo-random selection of a frequency from a hopping set of N frequencies such that over at least a portion of the time period T, the frequency selection is constrained to less than the N frequencies.

Abstract: A method for allocating network equipment of a cellular communication system to different users assigned to a particular cell thereby enhancing the capacity of the communication system without degrading the quality of communications provided to users of such a system. A user's signal is received and the strength of the signal is determined. The user is assigned to a first type or second type of network equipment based on a comparison the user's signal strength to upper and lower thresholds. The thresholds are defined by the network provider. When the signal strength is below the second threshold, the user is handed off to other network equipment of a neighboring cell. In this manner, the communication system is able to enhance its capacity while maintaining an acceptable quality of communications for its users.
