Abstract: Methods, apparatuses, and systems are described related to mapping special subframes in a wireless communication network. In embodiments, an eNB may assign demodulation reference signals (DM-RSs) and/or cell-specific reference signals (CRSs) to a downlink pilot time slot (DwPTS) of a special subframe responsive to a determined configuration of the special subframe. In embodiments, an eNB may bundle the DwPTS or an uplink pilot time slot (UpPTS) of the special subframe with another subframe for scheduling. In embodiments, a UE may estimate a channel associated with the special subframe based on DM-RSs and/or CRSs transmitted in another subframe. In embodiments, an eNB may exclude the DwPTS from scheduling for certain special subframe configurations if a new carrier type (NCT) is used. In embodiments, an eNB may exclude certain special subframe configurations from use for NCT communications. Other embodiments may be described and claimed.
Abstract translation: 描述了在无线通信网络中映射特殊子帧的方法,装置和系统。 在实施例中,eNB可以响应于所确定的特殊子帧的配置,向特殊子帧的下行链路导频时隙(DwPTS)分配解调参考信号(DM-RS)和/或小区特定参考信号(CRS)。 在实施例中,eNB可以将特殊子帧的DwPTS或上行链路导频时隙(UpPTS)与另外的子帧进行捆绑。 在实施例中,UE可以基于在另一子帧中发送的DM-RS和/或CRS来估计与特殊子帧相关联的信道。 在实施例中,如果使用新的载波类型(NCT),eNB可以排除对于某些特殊子帧配置的调度的DwPTS。 在实施例中,eNB可以排除某些特殊子帧配置用于NCT通信。 可以描述和要求保护其他实施例。
