Abstract: Techniques for supporting communication in an asynchronous TDD wireless network are described. In an aspect, downlink transmissions and uplink transmissions may be sent on different carriers in an asynchronous TDD wireless network to mitigate interference. In one design, a station (e.g., a base station or a UE) may send a first transmission on a first carrier in a first time period and may receive a second transmission on a second carrier in a second time period. The station may only transmit, or only receive, or neither in each time period. In one design, allocation of carriers for the downlink and uplink may be performed when strong interference is detected, e.g., by a base station or a UE. When strong interference is not detected, the first and second carriers may each be used for both the downlink and uplink.

Abstract translation: 描述了用于支持异步TDD无线网络中的通信的技术。 在一方面，下行链路传输和上行链路传输可以在异步TDD无线网络中的不同载波上发送以减轻干扰。 在一种设计中，站（例如，基站或UE）可以在第一时间段内在第一载波上发送第一传输，并且可以在第二时间段内在第二载波上接收第二传输。 车站只能在每个时段内传送，也可以只接收。 在一种设计中，例如由基站或UE检测到强干扰时，可以执行用于下行链路和上行链路的载波的分配。 当没有检测到强干扰时，第一和第二载波可以分别用于下行链路和上行链路。
