Abstract: A method for communication includes a user equipment (UE) periodically awakening to monitor for a wake-up signal (WUS) in a wake-up signal search space, the wake-up signal having a shorter length than a length of a control channel communication to allow the UE to determine whether the UE should monitor for the control channel communication.

Abstract: 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. The apparatus may determine a narrowband TDD frame structure for narrowband communications. The apparatus may also determine a PUSCH format of a group of PUSCH formats for allocating at least one RU to a UE for a NPUCCH. In addition, the apparatus may allocate the at least one RU to the UE using the determined PUSCH format. In one aspect, the RU may include one or more subcarriers in each of one or more slots.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for implementing one or more ECCE index determinations for MPDCCH in special subframes in eMTC using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications may include determining a type of channel is scheduled to be transmitted across multiple subframes, determining a first subframe of the multiple subframes is of a first subframe type that is different than a second subframe type of one or more other subframes of the multiple subframes, and determining resources for a decoding candidate of a channel based, at least in part, on the first subframe type and the second subframe type.

Abstract: 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. The apparatus may determine to transmit a narrowband physical downlink channel in a subframe in a narrowband TDD frame structure of a plurality of narrowband TDD frame structures for narrowband communications. In addition, the apparatus may determine whether the subframe is a special subframe or a downlink subframe when the narrowband TDD frame structure includes one or more special subframes. Further, the apparatus may determine how to transmit a narrowband physical downlink channel based on the determination whether the subframe is a special subframe or a downlink subframe. Additionally, the apparatus may transmit the narrowband physical downlink channel.

Abstract: 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. The apparatus may determine a TDD mode for narrowband communications. The apparatus may determine a TDD frame structure for the narrowband communications from a group of narrowband TDD frame structures. In one aspect, at least one common subframe in each narrowband TDD frame structure in the group of narrowband TDD frame structures may be configured as a downlink subframe. The apparatus may transmit a PSS using the at least one common subframe in the narrowband TDD frame structure determined for the narrowband communications.

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: Certain aspects of the present disclosure provide techniques for transmitting and receiving self-contained transmissions for enhanced machine type communications (eMTC) in unlicensed spectrum (eMTC-U). An exemplary method includes a BS determining, based on a listen before talk (LBT) procedure, that a first portion of unlicensed radio frequency spectrum is available for a frame, transmitting, on the first portion of the unlicensed radio frequency spectrum, a control channel indicating a frame format of the frame or a grant of the first portion of the unlicensed radio frequency spectrum for the frame, and communicating with a user equipment (UE) according to the frame format or the grant during the frame.

Abstract: Aspects of the present disclosure provide techniques and apparatus for performing narrowband physical random access channel (PRACH) procedures in large cells. For example, aspects of the present disclosure provide techniques for narrowband PRACH procedures (e.g., narrowband internet of things (NB-IoT)) to accommodate larger RTTs (e.g., up to 100 km). In some cases, supporting larger RTTs may involve a base station altering its PRACH processing by performing a two-step process of, first, obtaining a frequency domain phase offset based on an uplink signal from a UE, which provides a fractional delay and, second, performing a time domain correlation for different timing hypotheses to determine a timing offset based on the uplink signal. Supporting larger RTTs may also involve enabling a new NPRACH format that may coexist with legacy 3.75 kHz resources.
