    • The invention relates to a method for selecting a channel quality reporting mode for reporting estimated channel quality and to a radio base station (100) adapted to select such a channel quality reporting mode. The reporting mode is selected from a list of predetermined reporting modes. The radio base station comprises a measurement unit (101) adapted to measure a traffic load in the cell (110) and a comparator unit (102) adapted to compare the measured traffic load with a predefined threshold. The radio base station (100) further comprises a selector unit (103) adapted to select a channel quality reporting mode based on a result from the comparison, and a transceiver (104). The transceiver (104) is adapted to send configuration information to a user equipment (120) (UE) to inform the UE of the channel quality reporting mode to use in order to enable the UE to report channel quality estimations of a set up communication channel.
    • 本发明涉及一种用于选择用于报告估计信道质量的信道质量报告模式和适于选择这种信道质量报告模式的无线基站(100)的方法。 从预定报告模式的列表中选择报告模式。 无线电基站包括适于测量小区(110)中的业务负载的测量单元(101)和适于将所测量的业务负载与预定阈值进行比较的比较单元(102)。 无线电基站(100)还包括一个选择器单元(103),该选择器单元(103)适于基于比较结果来选择信道质量报告模式,以及收发器(104)。 收发器(104)适于向用户设备(UE)发送配置信息以通知UE使用的信道质量报告模式,以便UE能够报告建立的通信信道的信道质量估计 。

    • 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.
    • 本发明涉及一种用于半持续调度,SPS传输中的负载均衡的方法和基站(14,700)。 该方法可以包括为用户设备(12,步骤204)激活下行链路或上行链路传输,并且在物理共享或控制信道(获得用户设备)上获得关于包括SPS传输的SPS传输或HARQ ACK / NACK响应的关于传输负载的信息 步骤206; 402; 406; 502,504,508,510)。 基于所获得的信息,确定T子帧内的哪个子帧,包括SPS发送的传输负载或在SPS物理共享信道上或物理控制信道上的SPS发送的HARQ ACK / NACK响应在持续时间内是最低的 的T个子帧(步骤208; 404; 408; 506,512,514)。 然后将SPS传输调度为在物理共享信道上具有最低SPS传输负载的所确定的子帧中有效,在子帧中有效的子帧导致在具有最低的SPS传输的子帧中发送针对SPS传输的HARQ ACK / NACK响应 在T个子帧的持续时间内对SPS传输的HARQ ACK / NACK响应(步骤210)。该负载平衡提供了许多优点,包括较少的推迟调度,较少未使用的子帧以及在所述信道上较少的冲突。

    • 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.
    • 在用于从蜂窝无线电系统的移动台请求信道质量指示(CQI)报告的方法和装置中,响应于来自移动站的传输的测量的块错误率(BLER)请求CQI报告。 根据本发明的一个实施例,如果移动站的BLER高于预定阈值C,则请求CQI报告。阈值C可以被设置为与BLER目标相关的值。 特别地,值C可以被设置为相同的值或者接近作为目标的尝试使CQI报告请求适应于基站知道该信道的BLER的值。 也可以将其设置为更高或更低,以考虑在下行链路中涉及上行链路资源和上行链路授权信令时可以提供多少报告基站估计的CQI。
