摘要： A plurality of base stations (BTS3, BTS4, 35) are operated in CDMA macrodiversity mode to communicate a message to a mobile station (11) via an air interface (13). If the message is successfully communicated to one of the base stations via a packet network (23), the base station communicates the message to the mobile station via the air interface using CDMA. Otherwise, the base station refrains from communicating any message to the mobile station.

摘要： Devices, systems and methods for estimating inter-frequency measurements used for radio network functions are disclosed. The systems and methods described allow systems to evaluate the quality of a second frequency by using offset adjusted measurements on a first frequency. By using the described methods, system capacity is increased by providing a 'low cost' measurement mechanism for support of handover that substantially balance the load between two or more frequency bands. By using the proposed method, handover can be performed more frequently and the interference within each frequency band can therefore be kept at a more optimal level.

摘要： The disclosure relates to a method (20) for initiating a blind handover of a terminal (2) in a wireless communications system (1). The terminal (2) is served by a first cell using a first frequency band and a first radio access technology, wherein the wireless communications system (1) employs a method for dynamically changing coverage in at least one of the first cell and a second cell. The method (20) comprises estimating (21) the coverage in the second cell, wherein at least one of a second frequency band and a second radio access technology of the second cell may differ from the first frequency band and the first radio access technology, an initiating (22) the blind handover for the terminal (2) to the second cell only if the estimated coverage in the second cell meets a criterion. A wireless communications system (1), computer programs and computer program products are also provided.

摘要： The power levels of signals transmitted by base stations in a communication are controlled. Power level control commands are transmitted from a remote station to base stations from which the remote station receives signals to control the power levels of the signals transmitted by the base stations. A determination is made whether the remote station simultaneously receives a first signal from a first base station and at least one second signal from at least one second base station that include substantially identical message information. The first and second base stations transmit first and second reports of power levels of the first and second signals, respectively, to the controller. The controller compares the first and second reports and transmits first and second commands for adjusting the power levels of the first and second signals to the first and second base stations, respectively. The power level control commands are transmitted from the remote station to the base stations less frequently during macrodiversity to reduce the signalling requirements between the controller and the base stations. Also, the step size of the adjustment of the power levels of the first and second signals by the controller is reduced during macrodiversity to reduce the signalling requirements. This power control method is particularly beneficial for a CDMA system.

摘要： A method and apparatus for minimizing interference in a wireless communication system. A base transceiver station transmits and receives over a first frequency band and a second frequency band. The maximum range of the first frequency band can be smaller than the maximum range of the second frequency band. Alternatively, the maximum range of the first frequency band can be larger than the maximum range of the second freqency band. Further, the maximum range of the second frequency band can vary based upon factors such as the capacity of the first frequency band and the amount of interference on the first frequency band. A control channel for the second frequency band which is measured for determining whether to handoff from the first frequency band to the second frequency band can be transmitted within the first frequency band.
