Abstract: Aspects of the present disclosure provide techniques for enhanced transmission time interval (TTI) bundling design for machine type communications (MTC). A method for wireless communications by a wireless device is provided. The method generally includes determining a mapping of one or more uplink or downlink channels to one or more fixed bundling sizes, wherein each of the one or more fixed bundling sizes indicates a number of transmission time intervals (TTIs) over which a channel should be transmitted and processing transmission of the one or more uplink or downlink channels based on the mapping.

Abstract: Certain aspects of the present disclosure provide techniques for uplink control information (UCI) transmission for overlapping physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resource assignments with repetition. A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving scheduling to transmit on the PUSCH in a first one or more slots associated with a first number of repetitions and scheduling to transmit on the PUCCH in a second one or more slots associated with a second number of repetitions. The scheduled transmissions overlap in at least one slot. The method includes determining which channel to transmit UCI on and which channel to drop for each of the first and second one or more slots. The method includes transmitting or dropping the UCI in the first and second one or more slots in accordance with the determination.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for coded-bit allocation for UCI segmentation. An exemplary method that may be performed by a wireless device generally includes generating coded bits of uplink control information (UCI) to be transmitted as one or more segments, applying one or more rules to ensure an integer number of bits are allocated to each of the one or more segments, and transmitting the UCI in the segments according to the assignment.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive when operating in a network that provides synchronization signals at a plurality of locations in a channel bandwidth, a common search space (CSS) indicator for a synchronization signal, wherein the CSS indicator indicates that the synchronization signal is not associated with a CSS for a downlink control channel. The user equipment may determine a location of the CSS for the downlink control channel based at least in part on the CSS indicator. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide methods and apparatus for selecting beamforming parameters for uplink transmissions based on an uplink reference signal. An example method generally includes identifying one or more parameters for beamformed transmission to a transmit receive point (TRP), transmitting a reference signal using beamforming in accordance with the identified parameters, and receiving, from the TRP in response to the reference signal, signaling for adjusting the one or more parameters for one or more subsequent beamformed transmissions.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may identify a potential collision between a scheduled legacy transmission time interval (TTI) communication and a scheduled shortened TTI (sTTI) communication, the legacy TTI communication having a legacy TTI duration that is longer than an sTTI duration associated with the sTTI communication. The apparatus may determine whether the legacy TTI communication is within a threshold time of being transmitted. The apparatus may transmit at least one of the sTTI communication, the legacy TTI communication, or any combination thereof, based at least in part on the determination.

Abstract: Aspects of the present disclosure provide techniques for design of synchronization signals for narrowband operation, which can be used for stand-alone/in-band/guard-band deployment. An example method is provided for operations which may be performed by a base station (BS). The example method generally includes generating a primary synchronization signal (PSS) utilizing a first code sequence and a cover code applied to the first code sequence over a first number of symbols within one or more subframes, generating a secondary synchronization signal (SSS) based on a second code sequence over a second number of symbols within one or more subframes, and transmitting the PSS and the SSS in the first and second subframes to a first type of a user equipment (UE) that communicates on one or more narrowband regions of wider system bandwidth.

Abstract: Methods and apparatuses are disclosed for multiplexing uplink control information and uplink user data in the same uplink slot. A scheduling entity may use a unified rule to map uplink control information (UCI) in a distributed fashion according to a predetermined step size on each orthogonal frequency division multiplexing (OFDM) symbol regardless of UCI types. The scheduling entity may use a unified rule to partition the UCI into two parts when frequency hopping is enabled, and use the same unified rule to map the UCI in each hop.
