Abstract: A User Equipment (UE) and a mobile communications network node perform or handle inter frequency measurements. The technology prevents overloading the UE with frequency measurement processing by allowing different requirements for measurements, i.e., measurement performance requirements on different frequencies, i.e., cells. When ordering the UE to perform inter frequency measurements, two or more separate neighbor cell lists may be used. This allows a UE having a certain processor capacity to perform measurement control for more cells and frequencies, i.e., measurements on more than two non-used frequencies, without increasing the processing load of the UE.

Abstract: The invention relates to a method for reducing interference between users in a mobile communications network (1) in which uplink transmissions from user equipment, UE (3), to a radio base station, RBS (5A, 5B), can be performed on at least two different carriers (C1, C2). The UE (3) support dynamic switching between CDM and TDM transmission mode and the RBS (5A, 5B) is arranged to dynamically set the mode of transmission for the UE (3). The method comprises the steps of: —identifying (S200) at least a first UE as a high data rate, HDR, UE currently requiring high data transmission rate; dedicating (S201) at least one of said at least two carriers (C1, C2) to said HDR UE for at least a first period of time (T), said at least one carrier (C1, C2) hereinafter being named clean carrier, and—allocating (S202) said at least first HDR UE to said clean carrier (C1, C2) during said at least first period of time (T).

Abstract: The invention relates to a scheduling of data transmissions in multi-carrier data transmission systems, e.g. multi-carrier W-CDMA systems. A method embodiment of performing one or more data transmissions in a multi-carrier data transmission network (100) comprises, in a transmitting device (102), the steps of requesting transmission resources from a resource granting device (106); receiving, in response to the request (120), one or more transmission grants (gr1-gr3) from the resource granting device (106), wherein each transmission grant (gr1) indicates a data rate (dr1) and a data class (CI1) granted for a specific transmission carrier (Cr1); and initiating one or more transmissions (122-126) of data associated with one or more of the granted data classes on one or more of the granted transmission carriers.

Abstract: The invention relates to a radio base station (102) and method in a radio base station of a cellular communications system (100) for controlling self-interference. The radio base station (102) supports communication with a user equipment (101) using multiple uplink and multiple downlink carriers (104a, 104b, 105a, 105b). The method comprises detecting a degraded downlink performance on a downlink carrier (105a) due to self-interference by determining that a set of predefined conditions applies. The method further comprises executing, in response to detection of the degraded downlink performance, an action to reduce self-interference between the uplink and downlink carriers (104a, 104b, 105a, 105b). The action is one of: uplink scheduling to reduce self-interference, deactivation of a secondary uplink carrier (14a, 104b), deactivation of a secondary downlink carrier (105a, 105b), and initiation of carrier reconfiguration to reduce self-interference.

Wireless communication between the first plurality of terminals and the network device is carried out using a plurality of carrier channels. The communication defines a first bandwidth. The method comprises the steps of receiving the request for change of bandwidth from the first terminal, evaluating current load on carrier channels in use by the first terminal, evaluating priority between all terminals using the carrier channels currently in use by the first terminal, evaluating capacity of all carrier channels available to the first terminal, and allocating a second bandwidth between the network device and the first terminal by allocating a new number of carrier channels. The present invention further relates to a network device and a device for communication.

Abstract: A method and system are provided for optimal routing of calls in an Internet Protocol-based Base Station System (IP-based BSS), whereby a plurality of new messages are introduced on the A-interface. One such message informs the BSS that the Circuit Identity Codes (CICs) included in the message can be connected to the BSS to provide optimal routing of one or more calls. Another such message informs the BSS that the CICs included in the message are to be restored as separate CICs on the A-interface. The provision of such messages overcomes the significant disadvantages of the existing and developing BSS implementations.
