摘要： User Equipment (700) reports single-cell or multi-cell channel state information to a base station (600) on a PUCCH Format 3 resource. The PF 3 resource selected depends on whether ACK/NACK needs to be reported simultaneously. Different coding and/or scrambling and/or Interleaving schemes are used depending on whether ACK/NACK bits are present, as well as the number of ACK/NACK and/or CSI bits. Resource compatibility is maintained independently of the details of coding, interleaving, or scrambling - that is, all formats can be orthogonally multiplexed onto the same time-frequency resources. The format used for CSI only is PUCCH Format 3c (PF 3c) whereas the PUCCH Format used for CSI and ACK/NACK is PUCCH Format 3b (PF 3b). PUCCH Formats 3b and 3c may be further differentiated depending on whether a CSI from a single or multiple cells are reported, or from which cells (PCell, SCeil) an ACK/NACK is reported. Ambiguity may be resolved by using different spreading codes for reference signals In PF 3b and 3c formats.
摘要翻译：用户设备（700）向PUCCH格式3资源上的基站（600）报告单小区或多小区信道状态信息。选择的PF 3资源取决于ACK / NACK是否需要同时报告。取决于ACK / NACK比特是否存在，使用不同的编码和/或加扰和/或交织方案，以及ACK / NACK和/或CSI比特的数量。与编码，交织或加扰的细节无关地维护资源的兼容性，也就是说，所有格式都可以被正交地复用到相同的时间 - 频率资源上。仅用于CSI的格式是PUCCH格式3c（PF 3c），而用于CSI和ACK / NACK的PUCCH格式是PUCCH格式3b（PF 3b）。可以根据来自单个或多个小区的CSI是否被报告，或从哪个小区（PCell，SCeil）报告ACK / NACK来进一步区分PUCCH格式3b和3c。可以通过对PF 3b和3c格式的参考信号使用不同的扩展码来解决模糊度。

摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：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。

摘要： In a communication system using HARQ1 the problem of false ACK detection when no ACK/NACK feedback is transmitted is solved sent by varying the reliability of the scheduling information transmitted to the user terminal on a downlink control channel depending on whether the user terminal is expected to use a first or second uplink channel for sending ACK/NACK feedback. When the user terminal is expected to use the first channel to send ACK/NACK feedback, the base station transmits scheduling information to the user terminal with normal reliability. When the user terminal is expected to send ACK/NACK feedback on the second uplink channel, the base station transmits the signaling information to the user terminal with enhanced reliability. The reliability of the signaling information can be increased, for example, by increasing the transmit power on the downlink control channel, increasing the aggregation level, or a combination thereof.
摘要翻译：在使用HARQ1的通信系统中，通过根据用户终端是否期望在下行链路控制信道上发送到用户终端的调度信息的可靠性来解决发送没有发送ACK / NACK反馈的错误ACK检测的问题使用第一或第二上行链路信道来发送ACK / NACK反馈。当用户终端预期使用第一信道发送ACK / NACK反馈时，基站以正常的可靠性向用户终端发送调度信息。当预期用户终端在第二上行链路信道上发送ACK / NACK反馈时，基站以可靠性增强向用户终端发送信令信息。信令信息的可靠性可以例如通过增加下行链路控制信道上的发送功率，增加聚合等级或其组合来增加。
