摘要： The present invention relates to allowing configuring CSI reporting (step S-224, 310) on radio resources that are allocated over a plurality of sub frames on Physical Uplink Shared Channel (PUSCH). Allocation of said radio resources (steps S-202, 404) can be performed by semi-persistent allocation or by using Transmission Time Interval (TTI) bundling. By using either semi-persistent scheduling or TTI-bundling as decided by an eNB (104, 204, 600) the UE (102, 202, 500) can be configured to report CSI (step S-224, 310) for a plurality of UL transmissions. By allocating radio resources by using semi-persistent scheduling, the signaling overhead, which can be substantial for dynamic scheduling of radio resources, decreases. By using TTI-bundling the coverage of the CSI-reports increases.
摘要翻译：本发明涉及允许在物理上行链路共享信道（PUSCH）上通过多个子帧分配的无线电资源上配置CSI报告（步骤S-224,310）。可以通过半持久分配或使用传输时间间隔（TTI）捆绑来执行所述无线电资源的分配（步骤S-202,404）。通过使用由eNB（104,204,600）所确定的半持久调度或TTI绑定，UE（102,202,500）可以被配置为针对多个服务器（102,202,600）报告CSI（步骤S-224,310） UL传输。通过使用半永久调度来分配无线电资源，对于无线电资源的动态调度可能是重要的信令开销减小。通过使用TTI捆绑，CSI报告的覆盖面增加。

摘要： The invention relates to a method in a radio base station for improving the frequency resolution in the reporting of CQI, from a UE, where each CQI report is constituted of frequency domain averaged CQI values, each value being calculated for a bin of resource blocks (RBs). The method comprises the steps of - receiving CQI reports from the UE constituted of frequency domain averaged CQI values, wherein the borders between the RB bins for consecutive CQI reports have been varied over time by the application of a RB offset value; - performing time domain filtering of subsequent CQI reports such that the CQI for the resource blocks are estimated by averaging the CQI values of consecutive CQI reports that overlap the same resource blocks; whereby an improved frequency resolution is achieved. The invention furthermore relates to a method in a UE, a base station and a UE.

摘要： Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal (200) is configured to effectively ignore 'UP' transmit power control commands in the event that the mobile terminal (200) is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal (200), a plurality of transmit power control commands are received. An accumulated power control value is adjusted (350) in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted (350) in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal (200) is not in a power-limited state. Transmit power settings for each transmission are calculated (360) based on the accumulated power control value and the one or more radio link parameters.

摘要： In a method and a device for requesting Channel Quality Indication (CQI) reports from a mobile station of a cellular radio system, the CQI reports are requested in response to a measured Block Error Rate (BLER) of transmissions from the mobile station. In accordance with one embodiment of the present invention a CQI report is requested if the BLER of the mobile station is above a predetermined threshold value C. The threshold value C can be set to a value related to the BLER target. In particular the value C can be set to the same value or as a value close the BLER that is targeted to try to adapt the CQI report request to how well the base station knows the channel. It can also be set higher or lower to also consider how much CQl reporting the base station estimates can be afforded when it comes to uplink resources and uplink grant signaling in the downlink.

摘要： The present invention relates to a method and a base station (14, 700)for load balancing in Semi-Persistent Scheduling, SPS transmission. The method can comprise to activate downlink or uplink SPS transmission for a User Equipment (12, step 204), and to obtain information about transmission load comprising SPS transmission or HARQ ACK/NACK responses to SPS transmissions, on a Physical Shared or Control Channel (steps 206; 402; 406; 502, 504, 508, 510). Based on the obtained information it is determined for which subframe within aduration of T subframes, the transmission load comprising SPS transmission or HARQ ACK/NACK response to SPS transmissions, on a Physical Shared Channel or on a Physical Control Channel is the lowest within the duration of T subframes (steps 208; 404; 408; 506, 512, 514). SPS transmission is then scheduled to be valid in the determined subframe having the lowest SPS transmission load on the Physical Shared Channelor to be valid in a subframe causing the HARQ ACK/NACK responses to the SPS transmissions to be transmitted in the subframe having the lowest of HARQ ACK/NACK responses to the SPS transmissions, within the duration of T subframes (step 210).This load balancing provides a number of advantages comprising less postponed scheduling, less unused subframes and less collisions on said channels.
