Abstract: The application relates to channel state feedback reporting in wireless communication networks and in particular to modifications of the procedure for reporting CSI as specified by section 7.2 of 3GPP TS 36.213 V10.3.0. and the corresponding RRC protocol as specified by 3GPP TS 36.331 V10.2.0. The current cycle for CSI measurement and reporting is such that the UE performs separate CSI measurements for each report. However, the coverage area of CSI measurement reporting is lower than other uplink reporting such as e.g. ACK/NACK on PUCCH which supports subframe repetition, leading to an imbalance. Therefore, it is rather clear that it is highly beneficial to support coverage extension for CSI reports. The issue then arises as to how to realize the CSI coverage enhancement on top of existing/evolving CSI reporting framework. The application proposes to realize said CSI coverage enhancement by reporting (450) the same CSI report multiple times from the UE (110) to an eNB (220).

Abstract: Apparatus and method for resource allocation are provided. An apparatus includes a controller which is configured to utilize a tree structure with more than one branch in the resource allocation of physical resource blocks, each branch including one or more legal starting positions for resource allocation. Each starting position is associated with a cluster of physical resource blocks, the number of starting positions being different on each branch. The size of the resource clusters of each branch is different. The controller is configured to denote each resource cluster with a predefined index, and allocate one or more clusters to user equipment uplink connection.

Abstract: A frame or a subframe including control information and data is transmitted using orthogonal frequency division multiple access (OFDMA). At least one different OFDMA parameter and/or format is applied to said control information than to said data. At a receiver the frame or subframe is processed by taking into account the application of the at least one different OFDMA parameter and/or format.

Abstract: There is provided a mechanism for controlling a procedure for requesting resources for a communication in a communication network by a terminal device or UE. When the UE has selected a target cell from a plurality of communication cells, a message such as a resource request. A controller of a cell, such as an eNB, scans the reserved resources for receiving a message such as the resource request from a UE. The message is decoded by using identification information of the own cell and identification information of UEs being valid in the own cell. Then, it is determined whether the received message indicates as the target cell the own cell, and whether the UE is a known UE allocated to the own cell. Based on this determination, the message such as the resource request is processed or another cell is informed thereabout.
