Title
(EN) POINT-TO-MULTIPOINT SHARED-ACCESS FULL-DUPLEX WIRELESS DUPLEXING SCHEME ASSOCIATED WITH SPATIAL DIVERSITY
(ZH) 与空间分集相关联的点到多点共享接入全双工无线双工方案
Abstract
(EN) A wireless communication network for communicating information between a base station and a plurality of UEs is described. In accordance with a first aspect, the base station concurrently transmits toand receives from a plurality of UEs using a spatial diversity and a frequency division multiplexing, FDM, communication. In accordance with a second aspect, the base station concurrently transmits to and receives from a plurality of UEs using a frequency division multiplexing, FDM, communication without spatial diversity. In accordance with a third aspect, the base station concurrently transmitsto and receives from a plurality of UEs using a spatial diversity and a time division multiplexing, TDM, communication. In accordance with a fourth aspect, the base station concurrently transmits toand receives from a plurality of UEs a time division multiplexing, TDM, communication without spatial diversity, and wherein the UEs employ beamforming for inter-UE-interference suppression.
(ZH) 描述了一种用于在基站和多个UE之间发送信息的无线通信网络。根据第一方面,基站使用空间分集和频分复用FDM同时向多个UE发送以及从多个UE接收通信。根据第二方面,基站在不使用空间分集的情况下使用频分复用FDM同时向多个UE发送以及从多个UE接收通信。根据第三方面,基站使用空间分集和时分复用TDM同时向多个UE发送以及从多个UE接收通信。根据第四方面,基站在不使用空间分集的情况下同时向多个UE发送以及从多个UE接收TDM通信,以及其中,UE采用波束成形进行UE间干扰抑制。
