Abstract: Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.

Abstract: Wireless communication devices are adapted to facilitate multiplexing of signals. According to one example, a wireless communication device can multiplex a first signal and a second signal for transmission across a first resource element and a second resource element. The first resource element may utilize a first subcarrier in a first symbol employing a first numerology. The second resource element may utilize a second subcarrier in a second symbol employing a second numerology that is different from the first numerology, where the second subcarrier overlaps in frequency at least a portion of the first subcarrier. The first and second symbols including the multiplexed first and second signals may subsequently be transmitted. Other aspects, embodiments, and features are also included.

Abstract: Aspects of the present disclosure provide a subframe structure for time division duplex (TDD) carriers that can be entirely self-contained. That is, information transmitted on a TDD carrier may be grouped into subframes, where each subframe provides communication in both directions (e.g., uplink and downlink) in a suitable fashion to enable such communication without needing any further information in another subframe. For example, a single subframe may include scheduling information, data information corresponding to the scheduling information, and acknowledgment information corresponding to the data information.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

Abstract: Certain aspects of the present disclosure relate generally to wireless communications systems, and more particularly, to soft combining of control information. For example, certain aspects provide a method for wireless communication. The method generally includes monitoring for control information in each of a plurality of physical downlink control channel (PDCCHs) during a different one of a plurality of time intervals, wherein the PDCCHs contain the same control information that indicates a resource allocation within a respective one of the time intervals for receiving one of a plurality of physical downlink shared channels (PDSCHs), wherein data in each of the plurality of PDSCHs is the same. In certain aspects, the method also includes soft-combining the plurality of PDCCHs to decode the control information, and decoding the control information based on the soft-combination of the plurality of PDCCHs.

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 features related to a single bit ACK/NACK feedback for CBG based transmissions in a communication system are described. In an aspect, a base station may transmit, to a UE, a set of CBGs of a TB including a first subset of CBGs and a second subset of CBGs, the first subset of CBGs being transmitted on at least partially punctured resources. The base station may receive an ACK/NACK from the UE based on the transmitted set of CBGs, and retransmit to the UE one of the full set of CBGs or the first subset of CBGs based the received ACK/NACK. In an aspect, a UE may decode the set of CBGs received from the base station, transmit ACK/NACK feedback based on a result of the decoding, and receive, based on the transmitted ACK/NACK feedback, a retransmission of either the full set of CBGs, or the first subset of CBGs.

Abstract: Various aspects described herein relate to techniques for improving ultra-reliable low-latency communications (URLLC) used in wireless communication systems (e.g., 5G New Radio). In an aspect, a method of wireless communications includes identifying at least a first hybrid automatic repeat request (HARQ) transmission and a second HARQ transmission, wherein at least one of the identified HARQ transmissions is for URLLC, receiving an indication including information of reference signal handling for the identified HARQ transmissions, and performing the reference signal handling based on the information.
