摘要： A radio network controller, RNC, 614, and a method therein, for enhancing reception quality of transmissions on an uplink control channel from a user equipment, UE, 613 to a serving base station, BS, 610. The RNC, the UE and the serving BS are comprised in a communication system 600. The method comprises, when conditions for boosting the uplink control channel are fulfilled, determining a boosting factor based on a ratio of path gains of a channel from the UE to the serving BS and of a channel from the UE to a non-serving BS 611, respectively, which non-serving BS is comprised in the communications system. The method further comprises transmitting the determined boosting factor to the UE, whereby the reception quality of transmission on the uplink control channel from the UE to the serving BS is enhanced by the UE boosting the control channel by means of the boosting factor.

摘要： Methods and apparatus are disclosed for transmitting data to a remote node via each of two or more transmitted carrier signals, wherein a distinct outbound packet data traffic channel is mapped to each transmitted carrier signal. In an exemplary method, aggregated control channel data is formed by combining control channel data corresponding to each of two or more received carrier signals, simultaneously transmitting traffic channel data to the remote node on each of the two or more outbound packet data traffic channels, and transmitting the aggregated control channel data using one or more physical control channels mapped to a first one of the transmitted carrier signals. In particular, these methods and apparatus may be applied to a multi-carrier High-Speed Packet Access (HSPA) system.

摘要： In MU-MIMO scenarios, a target terminal can be exposed to data streams intended for other terminals. If the target terminal is capable of interference cancellation, then a network node, such as a base station or RNC, can provide the target terminal with interference information so that the target terminal can efficiently cancel interferences due to these interfering data streams. The interference information may include one or more interfering configuration, each of which characterizes a related interfering data stream. The interference information can also include the identity of the other terminal that is the intended recipient of the interfering stream. The network node may determine whether the target terminal can benefit from the interference information. If so, the network node can provide the interference information to the target terminal.

摘要： A method of calculating combining weight vectors associated with a received composite information signal comprising at least one data stream transmitted from at least a first antenna and a second antenna is disclosed. The method starts with computing a parametric estimate of an impairment covariance matrix including at least a first impairment term associated with common pilots deployed by the first antenna and the second antenna respectively. The first impairment term captures effects of interferences between the common pilots, in addition to effects of interferences caused by each common pilot singly. The impairment covariance matrix further includes a data covariance term capturing effects of the at least one data stream and an interference term caused at least partially by contribution of thermal noise of receiver branches. Then the method computes the combining weight vector using the computed impairment covariance matrix.
