    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 a duration 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 Channel or 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.

    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: A method for performing link adaptation in association with scheduling a data channel for a cell in a base station of a cellular communication system, and an arrangement, suitable for performing such a method. The link adaptation method has link adaptation optimization purpose which is achieved by updating a link adaptation parameter on the basis of the load on the data channel and on the basis of the load of a control channel controlling the data channel in the cell. The method obtains a better trade-off between the spectral efficiency and the delay, due to re-transmissions.

    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 CQI reporting the base station estimates can be afforded when it comes to uplink resources and uplink grant signaling in the downlink.

To this end, information indicating packet queue time and queue buffer size is acquired. Further, it is determined, for each queue of the at least one terminal, whether either estimated data packet delay for any queued data packet exceeds a delay threshold value or whether number of data packets queued exceeds a buffer size, and if so, the data packets of each queue is scheduled for transmission from the at least one terminal as a respective single bundle of data.
