摘要： Techniques for managing preamble transmission and processing on a shared communication medium are disclosed. An access point or an access terminal, for example, may generate a preamble for silencing communication on a communication medium with respect to an upcoming data transmission, configure the preamble to identify one or more target devices for the silencing, and transmit the preamble over the communication medium in advance of the data transmission. Conversely, the access point or the access terminal may receive a preamble (as a receiving device) over a communication medium, identify one or more target devices for silencing communication on the communication medium with respect to an upcoming data transmission based on the preamble, and selectively silence communication over the communication medium based on itself (as the receiving device) being among the one or more target devices.

摘要： Aspects described herein relate to selecting a rank for wireless communications using multiple transmit antenna layers. A first effective throughput achievable using a first rank and based at least in part on a first block error rate (BLER) associated with the first rank can be estimated along with a second effective throughput achievable using a second rank and based at least in part on a second BLER associated with the second rank. The first rank or second rank is selected to be used for transmitting communications over multiple transmit antenna layers based at least in part on comparing the first effective throughput to the second effective throughput, and the selection can be indicated to a transmitting entity from which the communications over the multiple transmit antenna layers are received.

A base station may perform a channel access procedure on a shared radio frequency spectrum band using a first beam configuration. The base station may transmit, based at least in part on successful completion of the channel access procedure, a reservation request message (RRQ) to a user equipment (UE) using a second beam configuration, the second beam configuration comprising a beam width that is equal to or narrower than a beam width of the first beam configuration.

摘要： Methods, systems, and devices for wireless communications are described, and relate to a base station to communicating with a user equipment (UE) over a channel. A first device (for example, the base station or the UE) may use a trained neural network to estimate one or more link performance metrics associated with the channel. Predicting the link level performance may include determining one or more neural network weights associated with one or more input parameters associated with the channel to estimate the one or more link performance metrics. The first device may report feedback to the second device based on the estimated link performance metrics. Based on the feedback, the second device may adapt the link by adjusting channel parameters to improve the reliability or efficacy of later transmissions.

摘要： Aspects for balancing power output on the plurality of antennas for the transmission of a transport block are disclosed. In accordance with the present disclosure, a transmitter may balance the power output on a plurality of transmit antennas in a multiple-input multiple-output (MIMO) system by having a precoded data block bypass a virtual antenna mapping of the overhead channels (e.g., control channels). Additionally or alternatively, the transmitter may balance the power output on the plurality of transmit antennas by applying an inverse mapping parameter during the precoding process to the transport block to generate a plurality of inverse mapped precoded data blocks. In some examples, the inverse mapping parameter may be an inverse of the mapping parameter. Thus, in accordance with the present disclosure, precoding a transport block may include selecting a precoding weight for each of the plurality of antennas from an unrestricted precoding weight set.
摘要翻译：公开了用于平衡用于传输块的传输的多个天线上的功率输出的方面。根据本公开，发射机可以通过使预编码数据块绕过架空信道的虚拟天线映射来平衡多输入多输出（MIMO）系统中的多个发射天线上的功率输出（例如，控制通道）。附加地或替代地，发射机可以通过在预编码处理期间向传输块应用反映射参数来平衡多个发射天线上的功率输出，以生成多个逆映射预编码数据块。在一些示例中，反映射参数可以是映射参数的逆。因此，根据本公开，传输块的预编码可以包括从无限制的预编码权重集合中选择多个天线中的每一个的预编码权重。

摘要： Systems and methods facilitating feedback of robust channel state information (CSI), such as to provide full CSI feedback or otherwise providing CSI feedback, are described. CSI encoders and/or decoders used by network nodes may implement channel compression/reconstruction based upon neural-network (NN) training of collected channels. A structured payload having an interpretable payload portion and an uninterpretable payload portion may utilized with respect to CSI feedback. The channel compression provided according to some aspects of the disclosure supports feedback of robust CSI, in some instances including full CSI, as determined by a particular network node. Other aspects and features are also claimed and described.
