摘要： A method performed in a wireless network includes receiving signals within a downlink frequency domain to enable channel estimation and measuring two or more signals only for two or more frequency bands of the downlink frequency domain that correspond to two or more uplink frequency bands associated with a scheduling grant or channel allocation that correspond to physical uplink channel frequency bands. The method also includes calculating path loss values for each of the frequency bands and calculating a total power based on the path loss values corresponding to the frequency bands. The method further includes determining a power allocation per frequency band based on the calculated total power to be applied to an uplink transmission and allocating the total power.

摘要： An object of the present invention is to provide a mechanism for handling a handover in a more efficient way. The invention relates to a method in a mobility controller (180) in a radio access network for preparing a handover. The method comprises the following steps to be taken during data transmission between a mobile terminal (140) and a source base station (120), before the handover: Sending a request to a candidate base station (122), which request aims at measuring and reporting timing alignment to be used by the mobile terminal (140) when communicating with the destination base station (122) after the handover, if the candidate base station becomes the destination base station (122) after the handover; receiving a report from the destination base station (122) comprising said requested timing alignment; and when the destination base station (122) is selected among the at least one candidate base stations, sending a message to the mobile terminal (140) to use said timing alignment received from the destination base station (122) when communicating with the destination base station (122) after the handover.

摘要： According to the teachings presented herein, wireless communication network interference is reduced by sending handover measurement information from mobile stations in conjunction with sending uplink scheduling requests, and by correspondingly making combined handover and uplink resource scheduling decisions. In this context, the combined decision considers both the handover measurement information and the uplink scheduling request, and determines whether a serving cell grants or denies the request and whether handover from the serving cell to a neighboring cell is or is not initiated for the mobile station. The combined determination provides for timely handover of the mobile station, such as where the mobile station is operating near a cell edge and issues an uplink scheduling request to its currently serving cell.
