    • Embodiments of the invention describe a method for antenna selection (AS) in a wireless communication network, the network comprising user equipment (UE), configured to transmit a sounding reference signal (SRS) from a subset of antennas at a time without transmitting user data. The method transmits a first SRS from a first subset of antennas in a first subframe, wherein the first subframe does not include the user data, and transmits a second SRS from a second subset of antennas in a second subframe, wherein the second subframe does not include the user data. After receiving, in response to the transmitting the first SRS and the second SRS, information identifying an optimal subset of antennas from the first subset of antennas and the second subset of antennas, the method selects the optimal set of antennas such that the optimal subset of antennas is selected without transmitting the user data.
    • 本发明的实施例描述了一种用于无线通信网络中的天线选择(AS)的方法,所述网络包括用户设备(UE),被配置为一次从天线子集发送探测参考信号(SRS),而不发送用户数据 。 该方法在第一子帧中从第一子天线发射第一SRS,其中第一子帧不包括用户数据,并且在第二子帧中从第二天线子集发送第二SRS,其中第二子帧不 包括用户数据。 在接收到响应于从第一天线子集和第二天线子集发送第一SRS和第二SRS之后识别天线的最佳子集的信息时,该方法选择最佳天线组,使得最佳子集 在不发送用户数据的情况下选择天线。

    • Embodiments of the invention describe a method for antenna selection (AS) in a wireless communication network, the network comprising user equipment (UE), wherein the UE comprises a plurality of subsets of antennas including a selected subset of antennas and an unselected subset of antennas, wherein only the selected subset of antennas is used for transmitting user data, and wherein the UE is configured to transmit only from a subset of antennas at a time. The method transmits the user data from the selected subset of antennas within a set of subframes, and transmits a sounding reference signal (SRS) from the unselected subset of antennas within at least one subframe in the set of subframes to enable antenna selection for user data transmission.
    • 本发明的实施例描述了一种用于无线通信网络中的天线选择(AS)的方法,所述网络包括用户设备(UE),其中,所述UE包括多个天线子集,所述多个天线子集包括选定的天线子集和未选择的天线子集 ,其中仅选择的所述天线子集用于发送用户数据,并且其中所述UE被配置为一次只从所述天线子集发射。 该方法从一组子帧内的所选择的天线子集中发送用户数据,并且在该组子帧内的至少一个子帧内从未被选择的天线子集发射探测参考信号(SRS),以使能用于用户数据的天线选择 传输。
