  • Patent number: 11750339
    Abstract: Methods for wireless communications over a wideband carrier are provided. Time-frequency resources of the wideband carrier within a transmission time interval are divided into multiple time-frequency resource blocks. Each of the time-frequency resource blocks corresponds to a group of contiguous subcarriers of the wideband carrier and orthogonal frequency division multiplexing symbols. Data streams may be scheduled to be transmitted in different time-frequency resource blocks, and may be destined for different user equipments or the same user equipment. Baseband processing operations may be performed on data streams scheduled in different time-frequency resource blocks independently from one another. Separate control channels or one common control channel may be configured for data transmissions in different time-frequency resource blocks.

  • Publication number: 20230239843
    Abstract: In an embodiment, a user equipment (UE) receives, from an access node (AN), downlink control information (DCI) triggering a transmission of a sounding reference signal (SRS) of a SRS resource set. The DCI indicates a time-domain resource in available time-domain resources for transmitting the SRS resource set. The UE determines a position of the time-domain resource in the available time-domain resources based on the DCI, and transmits the SRS in accordance with the position of the time-domain resource. In another embodiment, a UE receives control information indicating a frequency resource in a carrier for transmission of one or more SRSs. The UE determines, based thereon, to segment the frequency resource into segments that each includes contiguous physical resource blocks (PRBs), and transmits a SRS in an orthogonal frequency division multiplexing (OFDM) symbol on a first segment and not on a second segment.

  • Publication number: 20230208578
    Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.
