Abstract: The invention relates methods for triggering channel quality feedback for at least one of plural component carriers of a communication system available for downlink transmission. The invention suggests a mechanism for triggering channel quality feedback from a terminal where the downlink control signaling overhead for the selection of component carrier(s) to be reported on is minimized. One aspect of the invention is a new interpretation of a predetermined format for dedicated control information comprising a CQI request flag, which is depending on the status of the CQI request flag. In case the CQI request flag is set at least one further bit of the dedicated control information is interpreted as information indicative of the one or more component carriers available for downlink transmission to the terminal and the terminal is providing channel quality feedback on the channel quality experienced on the indicated component carrier or component carriers.

Abstract: A user equipment UE is configured with an integer value N which defines an effective data rate. The network sends to the UE a grant for uplink transmissions that comprises a resource indication field that allocates N channels each having a same predetermined uplink format and payload capacity. The UE sends N bit sequences on the respective N channels, each bit sequence comprising data and the same predetermined uplink format. In various embodiments: the network specifically configures the UE to receive the predetermined format of the grant; the grant may have an indicator whether the channels are for new data and for the MCS to use; the N channels may be in a same or in adjacent sub frames regardless of the value of N; and there is one MAC header for all the N channels which the network reads as a single MAC PDU.

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 translation: 该应用涉及无线通信网络中的信道状态反馈报告，特别是3GPP TS 36.213 V10.3.0的第7.2节规定的用于报告CSI的过程的修改。 以及由3GPP TS 36.331 V10.2.0规定的相应的RRC协议。 CSI测量和报告的当前周期使得UE针对每个报告执行单独的CSI测量。 然而，CSI测量报告的覆盖区域低于其他上行链路报告，例如。 支持子帧重复的PUCCH上的ACK / NACK，导致不平衡。 因此，很明显，支持CSI报告的覆盖范围是非常有益的。 然后出现了如何在现有/不断发展的CSI报告框架之上实现CSI覆盖增强的问题。 应用提出通过从UE（110）向eNB（220）多次报告（450）相同的CSI报告来实现所述CSI覆盖增强。
