摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a narrowband TDD frame structure of a group of narrowband TDD frame structures for narrowband communications. The apparatus may transmit a series of repetitions of a narrowband physical downlink channel using the narrowband TDD frame structure. In one aspect, a first portion of repetitions from the series of repetitions may be transmitted in one or more first sets of downlink subframes using a first scrambling sequence. In one aspect, a second portion of repetitions from the series of repetitions may be transmitted in one or more second sets of downlink subframes using a second scrambling sequence.

摘要： There is a need to support TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine to receive a narrowband physical downlink channel in a first subframe in a TDD frame structure of a plurality of TDD frame structures for narrowband communications. The TDD frame structures may include one or more special subframes, and the first subframe may be a downlink subframe. The apparatus may receive the narrowband physical downlink channel in a special subframe of the narrowband TDD frame structure, if the number of downlink OFDM symbols in the special subframe is greater than a predetermined threshold.

摘要： Wireless communications systems and methods related to uplink control channel transmissions with user multiplexing and reference signal transmissions are provided. A first wireless communication device obtains an uplink control channel multiplex configuration. The first wireless communication device communicates, with a second wireless communication device, a grant indicating a plurality of resource blocks spaced apart from each other by at least one other resource block in a shared radio frequency band, the plurality of resource blocks scheduled for multiple wireless communication devices based on the uplink control channel multiplex configuration. The first wireless communication device communicates, with the second wireless communication device, a first uplink control channel signal in one or more of the plurality of resource blocks based on the uplink control channel multiplex configuration.

摘要： Methods, systems, and devices for multiplexing code block group (CBG) level and transport block (TB) level feedback are described. An example method includes receiving a set of TBs, generating a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and transmitting the bit sequence. Another example method includes transmitting a set of TBs, receiving a bit sequence providing CBG-level feedback on a first subset of the TBs and TB-level feedback on at least a second subset of the TBs, and retransmitting at least one CBG for each TB in the first subset of TBs and the second subset of TBs based at least in part on the bit sequence.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for applying rules to determine when to retune radio components of a user equipment (UE). Certain aspects of the present disclosure provide a method for wireless communications by a UE. The method includes determining first resources assigned to the UE in a first subframe and second resources assigned to the UE for uplink transmissions in a second subframe. The method further includes determining whether to retune radio frequency (RF) circuitry prior to transmitting in the second subframe based on at least one rule involving an overlap between the first resources and second resources.

摘要： Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a control resource set configuration for transmissions using a single carrier waveform. The control resource set configuration may include one or more pilot regions and one or more control channel regions. The UE may monitor one or more of the pilot signal regions to identify pilot signals based at least in part on the control resource set configuration, and decode one or more control signals in the control channel regions based at least in part on the pilot signals. The control signals may be included in a control channel region associated with the pilot signal region or in a shared control channel region.

摘要： Techniques and devices for wireless communications are described that provide for staggering sounding reference signal (SRS) transmissions in frequency across multiple orthogonal frequency division multiplexing (OFDM) symbols, which may allow multiple UEs to transmit SRS using a common listen-before-talk (LBT) gap for a LBT procedure. The techniques also provide for transmitting an SRS across multiple OFDM symbols using same frequency resources, and an orthogonal cover code (OCC) may be applied to the SRS transmission of each OFDM symbol, which may allow multiple UEs to transmit concurrent SRS using a common LBT gap.

摘要： There is a need to support narrowband TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In a further aspect, the apparatus may receive information associated with a narrowband TDD frame structure having a first contiguous uplink transmission duration. The apparatus may transmit a first portion of an uplink transmission comprising a first number of slots in the first contiguous uplink transmission duration. In certain aspects, the uplink transmission may have a duration longer than the first contiguous uplink transmission duration.
