    摘要： Signaling design for interlaced frequency divisional multiplex (IFDM) demodulation reference signals (DMRS) is discussed in which a dynamic indication is provided to a user equipment (UE) from a serving base station that allows the UE to configure transmission of DMRS according to either a single carrier frequency divisional multiplex (SC-FDM) or IFDM configurations, as indicated by the dynamic indication. The IFDM configuration may be applicable to either regular uplink subframes or within the uplink portion of special subframes. In some aspects, power boosting may be provided for the DMRS in order to equalize transmit power between decimated DMRS transmitted with the data tones. Additional aspects may also provide for different offsets to be used depending on the type of uplink control signal transmitted.

    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 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.

    摘要： Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive at least one bit indicating a particular set of control symbols, of a plurality of sets of control symbols, comprising a downlink control region identify a location of a demodulation reference signal (DMRS), associated with a data channel, based at least in part on the at least one bit indicating the particular set of control symbols comprising the downlink control region; and communicate on the data channel based at least in part on the DMRS. Numerous other aspects are provided.

    摘要： Techniques for synchronizing devices in a wireless network are described. In an aspect, a device determines a receive time for a base station, obtains a time offset for the base station from a network entity, and sets its transmit time based on the receive time and the time offset for the base station. The time offset compensates for the degree by which the base station is asynchronous with respect to a reference time, e.g., UTC time. In another aspect, a device determines and sends time difference information (e.g., a time offset or a TDOA measurement) for at least one base station to support synchronization of other devices. In yet another aspect, a network entity supports synchronization of devices, receives time difference information for at least one base station, and determines at least one time offset for the at least one base station based on the time difference information.
