Embodiment Construction

[0020] In the following description, for purposes of illustration and not limitation, specific details of specific embodiments of the technology are set forth. One skilled in the art will recognize that other embodiments may be used without these specific details. In other instances, detailed descriptions of well-known methods, nodes, interfaces, circuits, and devices are omitted so as not to obscure the description with unnecessary detail. Those skilled in the art will realize that the described functions may be implemented in one or more nodes. Some or all of the described functions may be implemented using hardware circuitry, such as analog and / or discrete logic gates, ASICs, PLAs, etc., interconnected to perform the specified functions. Similarly, some or all of the functions may be implemented using software programs and data in conjunction with one or more digital microprocessors or general purpose computers. Where nodes are described for communicating using an air int...

Abstract

The present disclosure provides a full duplex communication method implemented by a Radio Base Station (RBS) supporting Time Division Duplex (TDD) scheme and the associated RBS. The method comprises configuring a first logic cell and a second logic cell for the RBS by specifying a first downlink / uplink (DL / UL) configuration corresponding to the first logic cell and a second, different DL / UL configuration corresponding to the second logic cell. The method also comprises transmitting a first wireless signal to a first UE associated with one of the first and the second logic cells and receiving a second wireless signal from a second UE associated with the other of the first and the second logic cells simultaneously in a subframe, which is allocated for DL communication according to one of the first and the second DL / UL configurations corresponding to the one of the first and the second logic cells and is allocated for UL communication according to the other of the first and the second DL / UL configurations corresponding to the other of the first and the second logic cells. Self-interference suppression is performed to suppress interference from the transmission of the first wireless signal to the reception of the second wireless signal.

Description

technical field [0001] The present disclosure generally relates to the technical field of wireless communication systems, and specifically relates to a full-duplex communication method implemented by a radio base station (RBS) and related RBSs. Background technique [0002] This section is intended to provide a background to various embodiments of the techniques described in this disclosure. The description in this section may include concepts that could be practiced, but not necessarily concepts that have been previously conceived or practiced. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and / or claims in the present disclosure and is not admitted to be prior art by virtue of its mere inclusion in this section. [0003] Time Division Duplex (TDD) / Frequency Division Duplex (FDD) communication refers to sending and receiving data on different time / frequency resource units, in contrast, full-duplex communi...
