摘要： A method and apparatus for reducing an effect of user interference on other users in an uplink of a radio access network using interference suppression. A user, for example, the user experiencing the highest interference, is selected from a plurality of users using the radio access cell. A perceived Rise over Thermal value for the user after interference suppression is predicted in the event that scheduling grants to an interfering user in the radio access network are altered. On the basis of the prediction, scheduling grants to the interfering user are altered, thereby reducing the interference for the selected user.

摘要： A method for load scheduling in a WCDMA communication system utilizing GRake equalizing radio reception comprises estimating (210) of channel estimates for a plurality of users. Combining weights are established (220) for a GRake equalizing reception for the present received uplink digital radio signals. Function parameters of a predicted future load measure function is predicted (230) as a function of individual grants of the plurality of users based on at least the channel estimates and the combing weights, taking sensitivity for interference suppression provided by the GRake equalizing for each of the plurality of users into account. The predicting further comprises adaptation of the function parameters for changed load equilibrium levels caused by the individual grants of the plurality users. A set of grants for the users is selected (240) based on the future load measure function. Uplink load is scheduled (250) according to the selected set of grants.

摘要： Apparatus and method for reducing an air interface load in a communication network. A base station is provided with a receiver adapted to receive signals from a terminal via a Dedicated Physical Control Channel (DPCCH) and a second control channel. A measuring unit measures a signal to interference ratio (SIR) of the DPCCH. An effective SIR determining unit determines an effective SIR on the basis of the measured SIR of the DPCCH and an estimate of the SIR of the second control channel. A comparison unit compares the effective SIR with a target SIR, and a power determination unit determines a power control command for controlling power usage for the DPCCH on the basis of the comparison. A transmitter sends a message to the terminal, the message including the power control command. The invention allows the DPCCH power (or DPCCH SIR) operating point to be maintained at a low level.

摘要： The transport format (TF) (302) of a signal (108) may be blindly detected from a reduced set of TF hypotheses (606). In an example embodiment, a method (800) for the blind detection of a TF (302) of a signal (108) includes filtering (802) a set of transport format hypotheses to identify a reduced set of TF hypotheses (606)using one or more filtering schemes (610a, 610b, 610c). From the reduced set of TF hypotheses (606), a TF (302) that is associated with an interfering signal (204) is detected. The TF (302) includes a modulation (304) and a spreading factor (306) for the interfering signal (204). It may also include a number of channelization codes (308). In an example implementation, when an interfering signal (204) is to be canceled,symbols carried by the signal are detected using the detected TF (302). Example filtering schemes (610a, 610b, 610c) include filtering based on system design/operation, filtering based on known configuration information, filtering based on an expected level of interference contribution, and so forth.

摘要： The present invention relates to methods and arrangements for uplink retransmissions from a user equipment to a radio base station in a UTRAN with enhanced uplink. The UE transmits a subframe comprising physical control channel(s) and physical data channel(s) in an initial transmission. According to the present invention, one or more of the physical control channels are transmitted with a lower transmission power level in all or some of the retransmitted subframes in the uplink. This results in reduced control overhead (a smaller part of the transmission power resource is used for control signaling) and thus reduced interference from the overhead. At the same time, the transmission power resource no longer used for the physical control channel information, can be used to increase the transmission power level of the physical data channel information in these retransmitted subframes, which improves the uplink coverage.
