Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a UE or base station, may identify a rate matching resource set for a transmission time interval (TTI) of a shared channel, where the rate matching resource set includes a set of symbols of the TTI allocated for rate matching. In some cases, the wireless device may identify a rate matching configuration for the rate matching resource set based at least in part on a multi-TTI grant for the shared channel, and perform rate matching of a set of data for transmission via the TTI based on the rate matching resource set and the rate matching configuration. In some cases, the wireless device may transmit, or receive, the rate-matched set of data via the one or more TTIs, in accordance with the multi-TTI grant, based on communications with another wireless device.

Abstract: Wireless communications systems and methods related to communicating in a shared communication medium with flexible scheduling are provided. A first wireless communication device communicates, with a second wireless communication device during a reservation period, a channel reservation request for a first transmission opportunity (TXOP) in a spectrum. The first wireless communication device communicates, with the second wireless communication device during a response period in response to the channel reservation request, a channel reservation response. The first wireless communication device communicates, with a third wireless communication device during a first time period between the reservation period and the response period, a first communication signal.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
