Abstract: An evolved Node B (eNB) and method for coherent coordinated multipoint transmission with per CSI-RS feedback are generally described herein. The eNB may configure a first cooperating point and a second cooperating point to jointly transmit a multi-node channel-state information (CSI) reference signal (RS) (CSI-RS) in predetermined resource elements of a resource block. The eNB may receive CSI reports as feedback from user equipment (UE). The CSI reports may include a precoding matrix indicator (PMI) indicating relative phase information between the cooperating points based on the multi-node CSI-RS. The CSI reports for the multi-node CSI-RS may be restricted to a PMI of rank-1. The eNB may configure the cooperating points for a coherent joint transmission to the UE based at least on the relative phase information. The coherent joint transmission may also be jointly beamformed based on single-node PMIs.

Abstract translation: 这里一般地描述了用于每个CSI-RS反馈的相干协调多点传输的演进节点B（eNB）和方法。 eNB可以配置第一协作点和第二协作点以在资源块的预定资源元素中联合发送多节点信道状态信息（CSI）参考信号（CSI）参考信号（CSI）。 eNB可以从用户设备（UE）接收作为反馈的CSI报告。 CSI报告可以包括基于多节点CSI-RS指示协作点之间的相对相位信息的预编码矩阵指示符（PMI）。 针对多节点CSI-RS的CSI报告可能被限制在等级-1的PMI。 eNB可以至少基于相对相位信息来配置用于向UE的相干联合传输的协作点。 相干联合传输也可以基于单节点PMI联合波束形成。

Abstract: The embodiments described herein relate to a user equipment (“UE”) and a plurality of nodes in a wireless network. A UE may be adapted to receive from a node a discovery signal that includes a base sequence. The base sequence may distinguish a first group of collocated nodes, comprising a first cell cluster, from a second group of collocated nodes, comprising a second cell cluster. The UE may further be adapted to receive from the node an orthogonal sequence, also included in the discovery signal. The orthogonal sequence may distinguish a first cell from other collocated cells so that cells within a cell cluster are separately identifiable. In further embodiments, the conjugate of sequences may be used to increase the amount of sequences available to distinguish cells and/or cell clusters. Other embodiments are described herein.

Abstract: Technology for reporting periodic channel state information (CSI) is disclosed. One method can include determining a reporting period (Npd) of a user equipment (UE) for a serving cell. A Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell of the UE can be identified. A periodic CSI report for the serving cell can be transmitted, from the UE to the eNB, using a physical uplink control channel (PUCCH) on the primary cell according to the reporting period. The reporting period of Npd=1 can be used for the serving cell if the TDD UL-DL configuration of the primary cell is one of 0, 1, 3, 4, or 6 and all UL subframes of the primary cell in a radio frame are used for periodic CSI reporting.

Abstract: Embodiments of the present disclosure include methods and apparatuses, for a third generation partnership project (3GPP) enhanced NodeB (eNB) to transmit parameters of a wake-up procedure with a 3GPP user equipment (UE). After the transmission, the eNB may enter a low power state wherein it monitors for the wake-up signal from the UE, the wake-up signal being based at least in part on the transmitted parameters of the wake-up procedure. When the eNB receives the wake-up signal, the eNB may enter the high-power state and transmit a connection establishment signal to the UE.

Abstract: A generation node B (gNB) configured for aperiodic channel state information reference signal (CSI-RS) triggering and transmission may encode signalling for transmission to a user equipment (UE). The signalling to indicate an aperiodic Triggering Offset (aperiodicTriggeringOffset). The aperiodic Triggering Offset may comprise a slot offset. The gNB may encode a downlink control information (DCI) for transmission that may trigger transmission of a CSI-RS in one or more aperiodic CSI-RS resource set(s) (i.e., in one or more slots (n)). The DCI triggers transmission of the aperiodic CSI-RS within a triggered slot with the slot offset (i.e., the aperiodicTriggeringOffset). The gNB may transmit the CSI-RS in resource elements of the triggered slot in accordance with the slot offset, when CSI-RS resources are available in the slot at the slot offset. The gNB may postpone transmission of the aperiodically triggered CSI-RS to a first available downlink slot when the CSI-RS resources are not available in the triggered slot at the slot offset.
