    摘要： Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may In support multiple component carriers that may be used to transmit uplink transmissions. One carrier may be used at a time such that the may switch between the carriers based on an uplink transmission schedule. In some cases, switching may be limited by a consecutive uplink switching rule or UE capability. In some cases, the gap between two consecutive uplink carrier switching operations may be limited to a resource (e.g., slot, symbol), such that the UE may expect to perform at most one switching operation per resource. In some implementations, the gap between two consecutive uplink carrier switching operations may be limited to a duration (e. g., 14 symbols, 4 symbols), such that the UE may expect to perform at most one switching operation per a duration less than or equal to a threshold.

    摘要： Certain aspects of the present disclosure provide techniques for adaptive modulo base selection for non-linear precoding. Aspects provide a method for wireless communications that can be performed by a base station (BS). The BS adaptively selects a modulo base for a data stream for at least one user equipment (UE) in a transmission to one or more UEs. The BS selects the modulo base based on one or more parameters. The BS transmits a signal for at least one UE of the one or more UEs to identify the selected modulo base. The BS performs the transmission to the one or more UEs. The UE receives the transmission from the BS and the signal for the identification of the selected modulo base. Based on the signal, the UE determines the modulo base for at least one data stream in the transmission and decodes the data stream using the modulo base.

    摘要： Certain aspects of the present disclosure provide techniques for uplink scheduling for communication on an uplink from a user equipment (UE) to a base station (BS). The uplink scheduling is based on uplink transmission (UL Tx) switching time and/or uplink data preparation time of the UE. The uplink data preparation time is calculated based on the UL Tx switching time. For example, a UE can report to a BS at least one of an indication of a UL Tx switching time and an uplink data preparation time of the UE. In return, the UE can receive an indication of uplink scheduling from the BS, which the UE can use to communicate with the BS.
