Abstract: A method, apparatus and system for wireless communication are described. The method includes transmitting and receiving data to and from one or more wireless transmit/receive units (WTRUs) via an underlay system access link. The underlay system is non-standalone, and control information is provided from an overlay system. An underlay base station is linked to other underlay base stations to implement a mesh backhaul. The method also includes transmitting and receiving at least a portion of the data to or from an overlay base station via backhaul links and receiving control data from the overlay base station. The data is split at a packet data convergence protocol (PDCP) entity, and the PDCP entity terminates in the overlay base station and a radio link control (RLC) entity terminates in the underlay base station.

Abstract: Feedback information for multiple serving cells are transmitted on high speed dedicated physical control channel (HS-DPCCH). A slot format for transmitting feedback information is determined based on the number of configured secondary serving cells and whether multiple input multiple-output (MIMO) is configured in the serving cells. Spreading factor is reduced to 128 when two secondary serving cells are configured and MIMO is configured in at least one of the two configured secondary serving cells, or when three secondary serving cells are configured. The serving cells are grouped into feedback groups, each feedback group having one or more serving cells. Channel coding may be applied to feedback information for the feedback groups. The resulting encoded feedback information for the feedback groups is concatenated to form composite feedback information.

Abstract translation: 用于多个服务小区的反馈信息在高速专用物理控制信道（HS-DPCCH）上发送。 用于发送反馈信息的时隙格式基于所配置的辅助服务小区的数量确定，并且是否在服务小区中配置多输入多输出（MIMO）。 当配置两个辅助服务小区并且在两个配置的辅助服务小区中的至少一个中配置MIMO时，或者当配置三个辅助服务小区时，扩频因子减少到128。 服务小区被分组成反馈组，每个反馈组具有一个或多个服务小区。 信道编码可以应用于反馈组的反馈信息。 所产生的用于反馈组的编码的反馈信息被级联以形成复合反馈信息。

Abstract: Methods and apparatuses for millimeter wave (mmW) beam acquisition are disclosed. An apparatus may include a processor and a transceiver configured to receive configuration information from a first network node using a first radio access technology (RAT). The configuration information may include an index associated with a beam of a second network node and timing information corresponding to the first RAT. The second network node may use a second RAT. The apparatus may be further configured to transmit a measurement report to the first network node that includes a measurement of the beam and index associated with the beam of the second network node.
