Abstract: Method performed by a network node (110) for scheduling one or more bearers for transmission to or from a wireless device (120). The wireless device (120) is serviced by the network node (110). The network node (110) calculates (1001) a weight for each bearer of the one or more bearers. The calculating (1001) is based on an indication of a quality of service associated with information to be transmitted in each bearer of the one or more bearers. The network node (110) schedules(1003) the one or more bearers for transmission to or from the wireless device (120) based on the calculated weight. The calculated weight corresponds to a Listen-Before-Talk, LBT, setting. The LBT setting comprises an LBT algorithm and its corresponding one or more parameters.

Abstract: Channel-state information and hybrid-ARQ ACK/NACK information for multiple carriers are simultaneously transmitted using a PUCCH Format 3 structure, where the hybrid-ARQ ACK/NACK bits and CSI bits are separately encoded and interleaved. In an example method, a power control offset parameter is calculated (2110) as a linear combination of at least a number N, representing a number of channel-state information bits and a number M, representing a number of hybrid-ARQ ACK/NACK bits. The method continues with the calculating (2120) of a power level for a transmission on a physical uplink control channel (PUCCH), using the power control offset parameter. In some embodiments, encoded channel-state information and hybrid- ARQ ACK/NACK bits are then transmitted (2060) according to the calculated power level. In some embodiments, the linear combination is of the form aN + bM + c, where a, b, and c are non-zero constants.

Abstract: In one aspect, the teachings herein provide a method and apparatus for extending certain HARQ feedback procedures introduced in LTE Rel-10, which were defined for CA configurations involving TDD serving cells of the same UL/DL configuration, to the new, more complex CA configurations introduced in Rel-11, which involve the aggregation of interband TDD serving cells with differing UL/DL configurations. Such reuse enables reliant and efficient HARQ feedback signaling in LTE Rel-11, without substantially increasing the specification or implementation complexity of HARQ feedback signaling in LTE Rel-11, despite the decidedly more complex CA configurations introduced in LTE Rel-11.

Abstract: A base station (20A) is configured to transmit user data to a wireless device (16A) upon a first carrier (22). The base station (20A) identifies, from a set of transmission resources that is nominally allocated for transmission of user data upon the first carrier (22), a subset of transmission resources that is also nominally allocated for transmission of a reference or control signal either by the base station (20A) upon a second carrier (24) or by a neighboring base station (20B) upon the first carrier (22). The base station (20A) selectively transmits user data to the wireless device (16A) upon the first carrier (22) exclusive of this identified subset of transmission resources. The device (16A) in some embodiments obtains information indicating that the base station (20A) is selectively transmitting user data upon the first carrier (22) exclusive of the subset in this way. Based on this information, the device (16A) recovers user data received upon the first carrier (22) exclusive of the subset of transmission resources.

Abstract: The invention is a method and apparatus for signaling uplink control information in a mobile communication network using carrier aggregation. The signaling mechanism allows the transmission, on a single uplink component carrier, of control information associated with a downlink transmission on multiple aggregated downlink component carriers. Semi-statically reserved resources for the transmission of control information on the uplink component carrier may be dynamically shared byuser terminals that are assigned multiple downlink component carriers for downlink transmissions. Implicit or explicit resource indication can be used in combination with dynamic resource indication.

Abstract: In one aspect, the teachings herein describe an enhanced Reference Signal, RS, that is designed to be available for transmission in any symbol of a subframe. The enhanced RS may be an enhanced Sounding Reference Signal, SRS, or an enhanced DeModulation Reference Signal, DMRS. The enhanced RS provides an advantageous mechanism for channel capture in Listen- Before-Talk, LBT, scenarios, because subsequent to performing a successful Clear Channel Assessment, CCA, a node can begin transmitting the enhanced RS, to thereby capture the channel. The node can then transition into an actual data transmission on the channel according to whatever timing constraints are associated with the data transmission. In at least one embodiment, the enhanced RS is used for capturing an uplink channel on an LTE carrier operated in unlicensed spectrum, as part of a License Assisted Access, LAA, configuration.

Abstract translation: 在一个方面，本文的教导描述了被设计为可用于子帧的任何符号中的传输的增强的参考信号RS。 增强的RS可以是增强的探测参考信号，SRS或增强的去调制参考信号DMRS。 增强的RS提供了在Talk-Before-Talk，LBT，场景中的信道捕获的有利机制，因为在执行成功的清除信道评估CCA之后，节点可以开始发送增强的RS，从而捕获信道。 然后，节点可以根据与数据传输相关联的任何时序约束转换到信道上的实际数据传输。 在至少一个实施例中，增强型RS用于在作为许可辅助接入（LAA）配置的一部分的情况下捕获在非许可频谱中操作的LTE载波上的上行链路信道。
