    摘要: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for strategically placing a sounding reference signal (SRS) within a slot to improve the decoding timeline. Aspects of the disclosure further relate to wireless communication systems configured to optimize the physical downlink control channel (PDCCH) search space within a slot to improve the decoding timeline. Features may also include placing the SRS near the end of the slot, such as after the uplink user data traffic and the corresponding uplink demodulation reference signal (DMRS). In addition, features may also include identifying the PDCCH search space within the slot based on at least a slot index of the slot. Other aspects, embodiments, and features are also claimed and described.

    摘要: Certain aspects of the present disclosure relate to methods and apparatus relating to a long uplink burst channel design. In certain aspects, the method includes determining, based on a hopping pattern, a first set of frequency resources available for transmitting uplink control information (UCI) within a first portion of a transmission time interval (TTI) and a second set of frequency resources available for transmitting UCI within a second portion of the TTI. The method also includes transmitting the UCI using the determined first set of frequency resources and the second set of frequency resources.

    摘要: Certain aspects of the present disclosure provide techniques for processing reference and data signals for uplink transmission. A method is provided for wireless communications. The method generally includes obtaining different sets of samples for at least one of: a data signal or a reference signal; spreading the different sets of samples for the at least one data signal or reference signal using separate discrete Fourier transform (DFT) processing blocks; interlacing the spreaded sets of samples by assigning the spreaded sets of samples from each of the separate DFT processing blocks to equally spaced tones; and transmitting the at least one data signal or reference signal on the assigned tones in an orthogonal frequency division multiplexed (OFDM) symbol.

    摘要: A new design for an uplink control channel is provided. A User Equipment (UE) determines, based on a tone mapping pattern from a plurality of tone mapping patterns for an uplink control channel, resources for transmitting the uplink control channel, and transmits the uplink control channel using the determined resources. A Base Station (BS) determines a tone mapping pattern from a plurality of tone mapping patterns for an uplink control channel, and transmits information regarding the determined tone mapping pattern to at least one UE. The BS receives the uplink control channel based on the tone mapping pattern.

At a user equipment (UE), a method and apparatus may include receiving, from a network entity, a transmission configuration indication including a DMRS pattern for configuring DMRS transmission on a communication channel. The method and apparatus further includes transmitting or receiving a DMRS to or from the network entity on the channel in accordance with the DMRS pattern. At a network entity, a method and apparatus may include transmitting, to a UE, a transmission configuration indication including a DMRS pattern for configuring DMRS transmission on a communication channel. The method and apparatus further includes transmitting or receiving a DMRS to or from the UE on the channel in accordance with the DMRS pattern.

    摘要: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may precode sounding reference signals using an interference covariance matrix to report channel quality information to a base station. For example, a UE may receive an indication of a future time from a base station. The future time may correspond to a future time for which the UE may predict an interference covariance matrix. In some cases, based on receiving the indication, the UE may monitor for interference in one or more interference measurement resources. In some examples, the UE may then determine the predicted interference covariance matrix and may transmit a sounding reference signal to the base station. The sounding reference signal may be precoded based on the predicted interference covariance matrix. In some cases, the UE may receive a downlink signal from the base station at the future time or at a second time.
