Abstract: An example implementation includes determining, by a user device, that the user device is a low-latency mode user device; receiving a downlink data block in downlink subframe n; determining a hybrid automatic repeat request (HARQ) feedback for the data block; determining, by the low-latency mode user device, an uplink subframe n+k at a HARQ feedback offset of k subframes from subframe n, and one or more uplink HARQ resources for the uplink subframe n+k reserved for the HARQ feedback from the low-latency mode user device; and transmitting, by the low-latency mode user device, the HARQ feedback via subframe n+k and the one or more uplink HARQ resources.

Abstract: There is provided a method for defining at least one channel reservation window the method comprising: setting length for each of the at least one channel reservation window such that each channel reservation window comprises a plurality of sub-frames; dividing the length of each channel reservation window into a transmission part and an idle part, wherein the idle part consists of one or more symbols in one sub-frame; maximizing, at a symbol level accuracy, the length of the transmission part such that a ratio between the length of the idle part and the length of the transmission part fulfills a predetermined criterion; and concatenating the transmission part and the idle part so as to form the channel reservation window.

Abstract: Resources for reference signalling on at least one component carrier of a plurality of aggregated component carriers can be determined by a station. Information indicative the at least one component carrier and the associated resources is then communicated to another station for configuration of the other station. A trigger is then sent for reference signalling, and in response to the trigger, at least one reference signal is sent from the other station using the indicated at least one component carrier and resources.

Abstract: Methods, apparatuses, and computer program products for defining ARO values in TDD are provided. One method includes defining acknowledgement (Ack)/negative acknowledgement (Nack) resource offset (ARO) values in time division duplex (TDD) with a first set of values and a second set of values. The first set of values contains negative values and is used to offset hybrid automatic repeat request (HARQ) acknowledgment (ACK) resource determination so that HARQ-ACK is transmitted on physical uplink control channel (PUCCH) resources corresponding to another downlink subframe, and the second set of values contains values between −2 and 2.

Abstract: Apparatuses and methods for transmission power control are disclosed. A given transmission resource and a first transmission power are determined (202, 204) for transmission. Prior to transmitting on the given transmission resource it is determined (206) whether the resource is occupied or unoccupied. Upon detecting that the resource is occupied, a second, reduced transmission power is determined (210) such that a transmission using the second, reduced transmission power would not render the resource as occupied. The determination of the second transmission power is based at least partially on a predetermined maximum transmission power reduction value. Transmission (212) is done utilising the given transmission resource using the second transmission power according to the determination.

Abstract: Disclosed are a method and a corresponding apparatus relating to wireless telecommunication systems and more particularly to efficient resource allocation schemes supporting transmission of multiple periodic channel state information (CSI) reports on the physical uplink control channel (PUCCH) during the same subframe while maintaining single carrier properties of the transmitted signal. The method includes determining that at least two reports to be transmitted on an uplink resource collide with respect to the uplink resource, applying at least one resource selection policy to the at least two reports and selecting a resource to be used for transmitting a plurality of the at least two reports.

Abstract: The disclosure relates to the allocation of resources for wireless communications. An index for an uplink control resource is determined in accordance with a predefined rule. The determining takes into account an index associated with a physical downlink resource and the amount of downlink resources to be mapped on the uplink control resource.

Abstract: A base station determines a first set of PUCCH resources to use for a first set of UEs to send acknowledgment information to the base station for a first group of DL subframes. The first set of PUCCH resources starts at a first index. The base station determines a second set of PUCCH resources to use for a second set of UEs to send acknowledgment information to the base station for a second group of DL subframes. The second set of PUCCH resources starts at a second index. The UEs in the first set only use the first set of PUCCH resources. The UEs in the second set use the first and second sets of PUCCH resources. For an UL reception, acknowledgement information is received from the first UEs using the first set of PUCCH resources and from the second UEs using the first and second sets of PUCCH resources.

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。
