Abstract: In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.

Abstract: Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) (10), measured at two points. UE speed estimates are taken at both the UE (10) and base station (12), and the two speeds compared. If the speeds match (or differ by less than a predetermined amount), one or more mobility parameters are adapted based on the UE speed. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, β, measurement period (Tm), handover prohibit timer, MeasurementReportingmargin, HOmargin, hysteresis, and the like. The UE speed comparison may be performed at the UE (10) or at the base station (12). In one embodiment, a plurality of UE speed ranges are defined (e.g., low, medium, high), with corresponding mobility parameter values associated with each range.

Abstract: The technology applies to a cellular radio network where each cell area is associated with a radio base station in which mobile terminals communicate with at least one of the base stations over a radio interface. The mobile terminals perform mobility-related measurements on downlink signals received from a corresponding neighbor cell during time slots configured for downlink transmission measurement. A configuration node receives input information, and based on that received input information, determines measurement time slot configuration information. The node provides the measurement time slot configuration information to the base stations so that the base stations may signal the measurement time slot configuration information to mobile terminals.

Abstract: The present invention relates to exchanging a cell-specific parameter such as the A-MPR, comprising information related to a required additional maximum power reduction of a UE transmitter between networks nodes. The networks nodes may be radio base stations or other network nodes such as radio network controllers or core network nodes exemplified by access gateways (aGWs). By exchanging this cell-specific parameter with information of the required additional maximum power reduction between the network nodes, the cell-specific parameter is provided to the radio base station of the serving cell which implies that the serving cell can send the cell-specific parameter of the target cell to the UE prior to the handover from the serving cell to the target cell. This result in that the UE can start transmission to the target cell with the correct cell-specific parameter and the out-of-band emission requirements can be fulfilled in the target cell.

Abstract: A user equipment performs downlink measurement on neighbour cells, but the measurement performance on a target cell (in terms of measurement period/sampling/accuracy etc) is dependent on the relative performance difference between the target cell and a reference cell. The reference cell may be the serving cell, or may be the strongest cell. The network is thus able to keep track of the required number of target cells without degrading the measurement performance of important cells. The UE on the other hand is still able to save its battery as much as possible while making full use of DRX.

Abstract: A MIMO-capable base station allocates a maximum transmission power budget to each of its antennas. For serving each of one or more MIMO and non-MIMO users, one or more carriers are allocated. For each carrier, information about an amount of allocated MIMO and non-MIMO user resources associated with the carrier is used to derive coefficients. Each coefficient corresponds to a unique one of the antennas, and represents a proportion of a maximum power budget for the carrier. For each carrier, the coefficients and the maximum transmission power budget for the carrier are used to derive a maximum transmission power budget for each of the antennas. For each antenna, a total maximum transmission power budget for the antenna is derived by combining the derived maximum transmission power budgets of the carriers transmitted on the antenna. The total maximum power budget of the antenna should not exceed a limit for the antenna.
