Abstract: The embodiments of the invention provide at least a method and apparatus to schedule an uplink communication from a user equipment of a plurality of user equipment; identify one or more candidate cells to support the uplink communication from the user equipment; send a request to the identified one or more candidate cells for requesting at least one of antenna data and pilot symbols from the one or more candidate cells for the uplink communication from the user equipment; and in response to the request, receive the uplink communication from the user equipment via a coordinated multi-point operation using at least in part a reception cells of the one or more candidate cells. Further, to receive, by one or more candidate cell, from a serving cell a request for at least one of antenna data and pilot symbols from the one or more candidate cells for a scheduled uplink communication from a user equipment to the serving cell; and in response to the request, provide the at least one of antenna data and pilot symbols for the uplink communication from a user equipment to the serving cell.
Abstract translation: 本发明的实施例至少提供了一种从多个用户设备的用户设备调度上行链路通信的方法和装置; 识别一个或多个候选小区以支持来自用户设备的上行链路通信; 向所识别的一个或多个候选小区发送请求，用于从所述用户设备向所述一个或多个候选小区请求用于所述上行链路通信的天线数据和导频符号中的至少一个; 并且响应于该请求，至少部分地使用一个或多个候选小区的接收小区，经由协调的多点操作从用户设备接收上行链路通信。 此外，为了从用户设备向所述服务小区的调度的上行链路通信，从一个或多个候选小区向所述服务小区接收来自所述一个或多个候选小区的天线数据和导频符号中的至少一个的请求; 并且响应于该请求，将用于上行链路通信的天线数据和导频符号从用户设备提供给服务小区。

Abstract: In accordance with example embodiments of the invention there is at least an apparatus and a method to perform determining, by a network node, a repeater, and/or a user equipment of a communication network, a configuration message comprising an identified frequency range of at least one of a first communication link between a donor and a repeater or a second communication link between a user equipment and the repeater for a repeat transmission in the communication network; and communicating with at least one of the repeater or the user equipment an indication of the configuration message for configuration at the repeater and the user equipment of the at least one set of sub-carriers mapped with the at least one physical channel for the repeat transmission, wherein the configuration message is using at least a different frequency offset of supported radio frequency resources to map at least one set of sub-carriers of the at least one of the first communication link and the second communication link with at least one physical channel in supported radio frequency resources of at least one of the first communication link or the second communication link, and mapping comprises performing spectral modification of resources to cause at least one of: sub-carrier shifting, wherein a sub-carrier is selected for the repeater to frequency shift to another part of the spectrum, based on instructions by the network node, sub-carrier inversion, wherein sub-carriers' indices are inversed, based on an on/off decision by the network node, and wherein the spectral modification is causing the at least one set of sub-carriers with the at least one physical channel to have different spectral properties as compared to a target set of sub-carriers associated with at least one of the user equipment or the repeater.

Abstract: An aggregation unit includes a transceiver configured to transmit unique signals to a plurality of transmission reception points (TRxPs) for transmission by the plurality of TRxPs and receive uplink signals received by the plurality of TRxPs from a user equipment. The aggregation unit also includes a processor configured to generate a sum of the uplink signals from a subset of the plurality of TRxPs. The subset is determined based on measurements of the unique signals performed by the UE. In some cases, the subset is determined by a baseband unit that receives a measurement report including the measurements performed by the UE. The transceiver is configured to transmit the sum of the uplink signals to the baseband unit over a fronthaul link.
