摘要： Certain aspects of the present disclosure propose methods and apparatuses for detecting whether a user device is scheduled for a single user (SU) multiple-input multiple-output (MIMO) communication mode or for a multi-user (MU) MIMO communication mode. In an aspect, a method for wireless communications is provided which includes measuring, at a first apparatus based on received pilot signals, a first receive power corresponding to a first channel associated with the first apparatus, measuring, based on the received pilot signals, a second receive power corresponding to a second channel associated with at least one potentially present second apparatus, measuring a residual interference based on the received pilot signals, and determining, based on at least one of the first receive power, the second receive power and the residual interference, whether to apply a MU detection or a SU detection for estimating data received at the first apparatus.

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a bitmap may be sent by a base station and/or a relay station to identify subframes of at least two types in multiple radio frames. For example, the bitmap may indicate whether each subframe covered by the bitmap is of a first type or a second type. UEs may use the bitmap to control their operation. For example, a UE may perform channel estimation or measurement for the subframes of the first type and may skip channel estimation and measurement for the subframes of the second type. In another aspect, a base station may transmit data and/or control information on resources not used by a relay station to transmit a reference signal. This may avoid interference to the reference signal from the relay station, which may improve performance for UEs communicating with the relay station.
摘要翻译：描述了用于支持无线通信系统中的中继站的操作的技术。在一方面，位图可以由基站和/或中继站发送以识别多个无线电帧中的至少两种类型的子帧。例如，位图可以指示位图所覆盖的每个子帧是否是第一类型或第二类型。 UE可以使用位图来控制它们的操作。例如，UE可以对第一类型的子帧执行信道估计或测量，并且可以跳过第二类型的子帧的信道估计和测量。在另一方面，基站可以发送关于中继站未使用的资源的数据和/或控制信息，以发送参考信号。这可以避免对来自中继站的参考信号的干扰，这可以提高与中继站通信的UE的性能。

摘要： Techniques for supporting operation of relay stations in wireless communication systems are described. In an aspect, a base station may transmit data to a relay station in a portion of a subframe instead of the entire subframe. The relay station may transmit control information during part of the subframe. The base station may transmit data to the relay station during the remaining part of the subframe. In another aspect, a target termination for a packet may be selected based on data and/or ACK transmission opportunities available for the packet. One or more transmissions of the packet may be sent with HARQ, and ACK information may be sent for the packet. The packet may be transmitted such that it can be terminated prior to the first subframe (i) not available for sending the packet or (ii) available for sending ACK information.
