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： According to embodiment of the present invention, there is provided a radio base station (20) and a corresponding method for estimating the quality of the uplink control channel. The method comprises measuring (32, 42) a quality parameter of the uplink data channel, and using (38, 50) this to estimate the quality of the uplink control channel. In one embodiment, measurements of the uplink control channel are taken and their reliability determined. If the reliability is low (i.e. below a threshold, or below the respective measurements taken on the uplink data channel), then measurements on the data channel are used instead of those made on the control channel to estimate the control channel quality.

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 some embodiments, there is provided a base station system configured to, among other things, (a) detect whether a particular UE is using too much power to transmit uplink data and (b) in response, transmit a message to the UE instructing the UE to detect a power control RS (PCRS) that is intended only for the particular UE. In some embodiments, the PCRS is transmitted such that the power (actual or nominal) of the PCRS as received by the UE is higher than the power of the previous CRS detected by the UE, thereby leading the UE to calculate a lower PL value, which can lead to the UE lowering its output power.
摘要翻译：根据一些实施例，提供了一种基站系统，其被配置用于（a）检测特定UE是否正在使用太多功率来发送上行链路数据，以及（b）作为响应，向UE发送指令 UE检测仅针对特定UE的功率控制RS（PCRS）。在一些实施例中，发送PCRS使得UE接收的PCRS的功率（实际或标称）高于由UE检测到的先前CRS的功率，从而导致UE计算较低的PL值，这可能导致UE降低其输出功率。
