    • Increased symbol length of uplink pilot time slots (UpPTS) in special subframes is disclosed in which a configuration of a first special subframe may be independent from configuration of a second special subframe in the same frame, such that the first UpPTS of the first special subframe is longer than the second UpPTS of the second special subframe. The second UpPTS of the second special subframe may also be longer than legacy UpPTS length in select configurations. A serving base station may select the special subframe configurations in order to balance sounding reference signal (SRS) capacity for compatible user equipments (UEs) and downlink throughput for legacy UEs. The selected special subframe configurations may be transmitted by the serving base stations. In additional aspects, compatible UEs may be configured with at least two separate SRS power control parameters for use in the additional and legacy UpPTS symbols.
    • 公开了特殊子帧中的上行链路导频时隙(UpPTS)的符号长度的增加,其中第一特殊子帧的配置可以独立于同一帧中的第二特殊子帧的配置,使得第一特殊子帧的第一UpPTS 比第二特殊子帧的第二UpPTS长。 第二特殊子帧的第二UpPTS也可能比选择配置中的传统UpPTS长度长。 服务基站可以选择特殊的子帧配置,以平衡兼容用户设备(UE)的探测参考信号(SRS)容量和传统UE的下行吞吐量。 所选择的特殊子帧配置可以由服务基站发送。 在另外的方面,兼容的UE可以配置有至少两个单独的SRS功率控制参数,以在附加的和传统的UpPTS符号中使用。

    • An eNodeB (eNB), Machine Type Communications (MTC) user equipment (UE) and method using a physical uplink control channel (PUCCH) in a non-legacy PUCCH region are generally described. The UE receives higher layer signaling indicating physical resource blocks in the PUCCH region and offsets in a cell- or UE-specific manner on a per-slot basis or, when in enhanced coverage (EC) mode, per-set of N subframes basis. The UE receives a resource allocation for a PUCCH in a PUCCH region separate from a legacy PUCCH region and reserved for non-legacy UEs. The UE transmits a frequency hopping PUCCH in the PUCCH region and uses shortened PUCCH format to accommodate an extended retuning time by puncturing a first and/or last symbol of at least one slot. If retuning, the UE drops a sounding reference signal transmission in the next subframe.
    • 通常描述在非传统PUCCH区域中使用eNodeB(eNB),机器类型通信(MTC)用户设备(UE)和使用物理上行链路控制信道(PUCCH)的方法。 UE接收指示PUCCH区域中的物理资源块的更高层信令,并且以每时隙为单位或UE特定方式偏移,或者当以增强覆盖(EC)模式为基础的N个子帧的每一组时。 UE在与传统PUCCH区域分离并且为非传统UE分配的PUCCH区域中接收用于PUCCH的资源分配。 UE在PUCCH区域中发送跳频PUCCH,并且使用缩短的PUCCH格式来适应扩展的重新调度时间,通过删除至少一个时隙的第一和/或最后一个符号。 如果重新调度,则UE在下一个子帧中丢弃探测参考信号传输。
