Abstract: A method and apparatus for controlling transmission power levels in a CDMA cellular communication system are disclosed, whereby a third (middle) control loop (30) is interposed between an inner loop (40) and an outer loop (20) to form a cascaded power control loop (10). Certain quality indicators are coupled to the outer loop (20) and middle loop (30). The outer loop (20) produces a quality target value for the middle loop (30). The middle loop (30) produces the SIR target value.

Abstract: A method and apparatus for controlling an amount of downlink power to be applied in each downlink transmission in a macro diversity radio system. Downlink power level is controlled in response to a quality measurement of a corresponding uplink. In accordance with exemplary embodiments, a path gain or a carrier-to-interference ratio of an uplink is measured at a base station in an active set, and subsequently used to proportionally govern a downlink transmission power level for a corresponding downlink. In such a fashion, each downlink handling a mobile station maintains a desired level of robustness, while avoiding introduction of unnecessary system interference.

Abstract: Se propone un metodo para adaptar parametros de asignacion de recursos para alcanzar una o varias metas de calidad con exactitud mejorada. Se introducen nuevas mediciones de informacion con base en lo que se conoce como informacion mutua, preferentemente a nivel de bloque. Las mediciones de informacion basada en MI de una transmision previa, la prediccion de canal de una transmision subsiguiente y uno o varios requisitos de calidad se utilizan para determinar la cantidad y tipo de recursos, por ejemplo, recursos de tiempo, frecuencia y potencia que deben utilizarse para la transmision subsiguiente. La asignacion de recursos puede comprender, por ejemplo, asignacion de potencia y/o adaptacion de enlace y la invencion permite una implementacion provechosa con adaptacion de enlace y asignacion de potencia cooperativas. El metodo propuesto es util con relacion a retransmisiones ARQ-HARQ.

Abstract: Circuitry, and an associated method for a multi-user communication system, such as a cellular communication system. Additional communication is selectively permitted in the communication system through operation of the circuitry. Levels of communication quality of ongoing communication in the communication system are determined. When a request is made to admit additional communication, the additional communication is admitted only when the level of communication quality is better than a selected threshold.

Abstract: The invention relates to a method of performing handover in a mobile radio system. The mobile radio system performs quality measurements on signals transmitted (300) between a mobile terminal and predetermined radio base stations. Handover is performed (301, 302, 303) when some of the measured signal strengths exceeds the signal strength for the radio base station to which the mobile terminal for the moment is set up, added to a handover value. The handover value is dependent on measured signal strengths and neighboring cell relation values. The neighboring cell relation values depend on a probability for handover to be performed from one radio base station to another radio base station in the mobile radio system.

Abstract: PCT No. PCT/SE95/00854 Sec. 371 Date Jan. 13, 1997 Sec. 102(e) Date Jan. 13, 1997 PCT Filed Jul. 13, 1995 PCT Pub. No. WO96/02979 PCT Pub. Date Feb. 1, 1996The invention relates to a method and to an arrangement for effecting base orthogonal channel hopping between mobile stations (MS1-MS3) and a base station in a radio communications system. Connections (F1-F3) having low attenuation are allotted a number of channels having high interference I (channel, t). Connections (F1-F3) that have higher attenuation are allocated a number of channels that have lower interference I (channel, t). A channel allocation means (211) in the base station functions to produce channel hopsequences which are transferred to hopsequence lists (204-206) in the mobile stations (MS1-MS3), via a control channel SACCH. The channel hopsequences are also transferred to corresponding hopsequence lists (201-203) in the base station. Attenuation of the connections (F1-F3) and interference on the channels I (channel, t) are measured continuously in the channel allocating means (211), wherein the best channels with respect to interference are used. The channel allocation means creates the channel hop sequences in accordance with the principle that the better a connection with respect to attenuation, the poorer the channels with respect to interference that are allocated to the connection.

Abstract: Methods, systems, and arrangements enable balanced base station transmitter output power levels with respect to a receiving mobile station in a macro-diversity communication by adjusting a base station transmitter output power level responsive to power control command(s) sent by the mobile station and the (current) transmitter output power level of the base station. In a fixed adjustment step embodiment, power level convergence is enabled by adjusting the transmitter output power level of a given base station by a greater amount (e.g., than the nominal amount) when a power control command orders a power adjustment of the transmitter output power level towards a reference level and by adjusting the transmitter output power level by a lesser amount when a power control command orders a power adjustment of the is transmitter output power level away from the reference level. A continuous adjustment step embodiment is also disclosed.

Abstract: A method for optimizing the use of channels, the changing of channels and handover procedures in a mobile telecommunications system for instance, wherein parameters belonging to the mobile telecommunications system generate the load values for the connections via different channels/base stations between subscribers in a public telephone network and mobile stations in the mobile telecommunications systems. Different kinds of parameters can be compared directly by means of the load values which are combined to provide a total load value for each connection. A first total load value is generated for a connection set-up between one of the subscribers and one of the mobile stations. The total load values for the connection are estimated for alternative channels/base stations and these total load values are compared with the first total load value. The system changes to the channel/base station that has the most favorable load value, on the basis of the comparison. The load values can also be used to optimize the resources within one or more base stations, so that the sum of the load values for the connections within one or more base stations will become the most advantageous.

Abstract: The present invention relates to a method in a wireless communication system and in particular better usage of available radio resources in such systems by controlling the party effects using user based scheduling back-off. The scheduling back-off according to the invention is based on providing and controlling the number of channels/frequencies/codes/timeslots or fractions of channel use to a terminal depending on information regarding radio channel quality obtained from the system.
