    • An eNodeB (eNB), user equipment (UE) and method for operating using a reduced data transmission bandwidth are generally described. The UE may receive downlink control information (DCI) that provides a resource allocation (RA) of a reduced physical resource block (PRBmin) of less than 1 PRB for communications in a PRB of a subframe. Whether the RA is localized or distributed may be predefined, configured via system information block or Radio Resource Control signaling, or indicated in the DCI format. The DCI format may specify the resources within the PRB allocated to the UE through a subcarrier block index and total number of subcarrier blocks or a bitmap corresponding to a unique block of subcarriers or block index. An order in a list of cell Radio Network Temporary Identifiers (RNTIs) may be used with a common RNTI to derive the reduced RA from a 1 PRB RA.
    • 通常描述eNodeB(eNB),用户设备(UE)和使用减少的数据传输带宽进行操作的方法。 UE可以接收下行链路控制信息(DCI),该下行链路控制信息(DCI)为子帧的PRB中的通信提供小于1个PRB的减少的物理资源块(PRBmin)的资源分配(RA)。 无论RA是本地化的还是分布式的,可以通过系统信息块或无线电资源控制信令来配置,或以DCI格式表示。 DCI格式可以通过子载波块索引和子载波块的总数或对应于子载波或块索引的唯一块的位图来指定分配给UE的PRB内的资源。 单元无线电网络临时标识符(RNTI)列表中的顺序可以与公共RNTI一起使用以从1个PRB RA导出减少的RA。

    • 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 may be in an enhanced coverage (EC) mode. The UE may receive 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 EC mode, per-set of N subframes basis. The UE may receive a resource allocation for a PUCCH in a PUCCH region separate from a legacy PUCCH region and reserved for non-legacy UEs. The UE may transmit a frequency hopping PUCCH in the PUCCH region and use 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 may drop 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可以处于增强覆盖(EC)模式。 UE可以接收指示PUCCH区域中的物理资源块的更高层信令,并且在每个时隙的基础上以小区或UE特定的方式偏移,或者当在EC模式下,基于N个子帧的每组。 UE可以在与传统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可以在PUCCH区域中发送跳频PUCCH,并且使用缩短的PUCCH格式以通过对至少一个时隙的第一和/或最后一个符号进行删截来适应扩展的重新调度时间。 如果重新调度,则UE可以在下一个子帧中丢弃探测参考信号传输。

    • Embodiments of a machine-type communication (MTC) User Equipment (UE) and methods for configuring a MTC UE using an evolved Node B (eNB) are generally described herein. A method for configuring a UE for communication performed by circuitry of an evolved Node B (eNB) may include broadcasting, from the eNB, a physical downlink control channel (PDCCH) transmission on a licensed band, transmitting, from the eNB to the UE, a physical broadcast channel (PBCH) transmission multiplexed with a machine-type communication (MTC) PBCH (M-PBCH) transmission, the M-PBCH transmission including a MTC master information block (M-MIB) in a MTC region of the licensed band, wherein the MTC region includes a subset of frequencies of the licensed band, and transmitting, from the eNB to the UE, a first data transmission on the MTC region in a downlink.

    • An enhanced NodeB (eNB), user equipment (UE) and method of Channel State Information (CSI) measurement and reporting using reduced bandwidth are generally described herein. The UE is preconfigured with a resource configuration information or the configuration information is transmitted to the UE from the eNB. The configuration information indicates a narrowband region on which to monitor for and receive physical downlink control and data channels and perform measurements for CSI computation. The region has a reduced bandwidth that is supported by the UE and is free from subbands outside of the region. The UE takes measurements of downlink transmissions using the assigned resources. The measurements are limited to subbands included within the region. The UE calculates the CSI based on an unrestricted time interval within subframes of the region and a restricted frequency interval free from physical resource blocks outside the region. The UE reports a region-specific wideband CSI that includes at least a region-specific wideband Channel Quality Indicator to the eNB.
    • 通常在此描述增强型节点B(eNB),用户设备(UE)以及使用减少带宽的信道状态信息(CSI)测量和报告的方法。 UE预先配置了资源配置信息,或者从eNB向UE发送配置信息。 配置信息指示在其上监视和接收物理下行链路控制和数据信道并执行CSI计算的测量的窄带区域。 该区域具有由UE支持的减少的带宽,并且不存在该区域外的子带。 UE使用分配的资源来测量下行链路传输。 测量被限制在该区域内包括的子带。 UE基于区域的子帧内的不受限制的时间间隔和区域外的物理资源块的限制频率间隔来计算CSI。 UE向eNB报告区域特定的宽带CSI,其至少包括针对eNB的区域特定的宽带信道质量指示符。
