摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine information that identifies a resource for transmitting an acknowledgment of a message associated with a random access procedure. The information that identifies the resource may be determined based at least in part on at least one of: a frequency band associated with the random access procedure, a resource associated with at least one message in a sequence of messages associated with the random access procedure, a payload of at least one message in the sequence of messages associated with the random access procedure, or a grant associated with another message in the sequence of messages associated with the random access procedure. In some aspects, the user equipment may transmit the acknowledgment based at least in part on the information that identifies the resource. Numerous other aspects are provided.

摘要： Aspects of the present disclosure relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink grant that does not include a downlink assignment index (DAI); determine a pre-defined bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the pre-defined bundle window. In some aspects, a UE may receive a downlink grant that does not include a DAI; determine a bundle window, associated with ACK/NACK multiplexing or bundling, based at least in part on receiving the downlink grant that does not include the DAI, wherein the bundle window is not pre-defined; and transmit ACK/NACK feedback to acknowledge or negatively acknowledge one or more downlink communications received in the bundle window. Numerous other aspects are provided.

摘要： Aspects directed towards new radio (NR) transmissions of uplink control information (UCI) are disclosed. In a particular example, a priority is assigned to each of a plurality of UCI components such that the priority is assigned according to at least one of a type or payload size respectively associated with each of the plurality of UCI components. The plurality of UCI components are then transmitted based on the priority respectively assigned to each of the plurality of UCI components.

摘要： Aspects of the disclosure relate to implied and explicit mapping of uplink (UL) resources for acknowledgment communications from a user equipment (UE). In some examples disclosed herein, implied mapping may include indexing of information elements in a downlink (DL) communication. The explicit mapping may include information elements in the DL communication configured to explicitly provide a location of an UL resource. Other aspects, embodiments, and features are also claimed and described.

摘要： A user equipment (UE) may transmit a control channel and a data channel using contiguous resource allocations of a portion of a slot. The control channel may be associated with control channel power spectral density (PSD) and the data channel may be associated with a data channel PSD. When a difference between the control channel PSD and the data channel PSD exceeds a maximum delta value, the UE may experience degraded performance as a result of tonal interference and/or the like. In some aspects, the UE may determine a control channel transmit power for the control channel and a data channel transmit power for the data channel. The control channel transmit power and the data channel transmit power may be determined such that the maximum delta value is not exceeded and that a threshold relating to a link budget is satisfied, thereby ensuring that performance is not degraded.

摘要： Aspects of the disclosure relate to multiple-input multiple-output (MIMO) signals, and the determination of a precoding matrix for configuring the MIMO signals. An uplink traffic channel may be configured utilizing orthogonal frequency division multiplexing (OFDM) waveform. Determination of the precoding matrix may be based at least in part on an estimate of the uplink carrier, where the uplink carrier estimate is based at least in part on a downlink reference signal, exploiting channel reciprocity in a time division duplex (TDD) carrier. Determination of the precoding matrix may further be based at least in part on a cross-correlation matrix Rnn or a whitening matrix determined by a scheduling entity. Other aspects, embodiments, and features are also claimed and described.
